Return Sum Of Array Within Matrix Based On Independent Value?
Mar 8, 2013
I'm trying to write a formula that will return the sum of multiple cells within a larger matrix, based on a number that is manually inputted into a separate table. As you can see in the top below, I have data that is grouped by both "Zone" and by individual "Stations". The Zones/Stations on the y-axis are "Start" points, while the Zones/Stations on the x-axis are "Finish" points. What I'd like to be able to do is input a Zone ID number into the bottom table (Shown as "1" below) and have the formula either return the greatest sum of "Finish" numbers. In this example, the greatest sum is 12, which is all numbers going from Station 1 and 2 in Zone 1 to Stations 1/2 in Zone 2 (3+2+4+3). In the bottom table, you'll see the "Greatest Finish" as "2", which is Zone 2. And the total from this sum is 12, as described previously. If there is a way to return either the "Total #" or "Greatest Finish" zone.
The actual matrix I am working with is much larger (150x150), and not all zones have the same amount of stations. I'm assuming this might complicate things a bit.
Finish
Zone 1
Zone 1
Zone 2

I am looking up a risk matrix to return the risk rating... it is very simple, it works on one sheet, but on a different sheet (looking up different data, but same basic format) it returns exactly the opposite rating.
My formula is: =INDEX($G$6:$K$10,MATCH(I19,$G$5:$K$5,0),MATCH(J19,$F$6:$F$10,0))
Here is F4 to K10
I have data validation on I19 and J19 based on the cells below
Consequence
Priority
Very Low
Low
Medium
High
Very High
[Code] ..........
BUT... when I put Very Low and Very Low in the two cells (I19 and K19) I get Very High as the return.

Using VBA, I wish to work out the inverse matrix of a large matrix (100*100), but keep getting the # Num! Error. I am using the minverse function. I have defined variable as "variant", does this give me the same possiblities in terms of number size as the variable "Double"?

In the attached spread sheet, i have two set of data, for two different months.Columns A to D have the value for the first month and columns F to I have the values for the second month. In the first set of Values i have the dollar value in the column "D" and in the second set of values i have the dollar value in column "F".
I want a macro, to compare these two cells and arrange the data accordingly. If both the values are the same, then both the lines corresponding to the values can remain in the same row. If one value is greater that other, then the set of values which have the lower dollar value should come to the next row. I have attachec the sample data. The lines highlighted in green is the raw data and the one in yellow is the finished data.

I want to search a data set and return the maximum value based on 3 criteria using (array) formulas.
Say the data set contained the following:
Row 1: column headings (date, name, data 1, data 2, data 3, etc)
Column A: dates
Column B: names
Columns C through G: data
I want to find the maximum value for a given name, in a certain month, and a nominated data column (e.g. data 2). For example:
Month = June
Name = Geoff
Data column = Data 2
Max value = ????
All of the data in the data columns is numeric.

I can manage an array formula that returns a value based on a criteria. Simple. But I want to add in an additional couple of criteria. Now I'm stuck....
My sheet looks at a manually entered postcode, finds out what region this is in, and returns a list of postcode I have defined as being in that region. (So the postcode WF1 3JY would return a region of Yorkshire, and list postcodes of WF, BD, L, etc)
I also have a list of engineers, with a column for their home postcode.I want to be able to list all the engineers from my list whose home postcode matches any of the values on the already created list from the postcode and region entered. So far I have this, which finds me all the engineers for just one postcode area.

I am trying to calculate a matrix of array formulas that is roughly 365 x 137, or about 50,000 cells being calculated from a range of roughly 12,000 x 137. There are multiple if statements within the array formula, and then those 50,000 cells are referenced to another, but smaller matrix of array formulas (25 x 137). Each of these matrix sets is for one year, and there are three years that need calculated.
Problem: When calculating the 50,000 cells it takes roughly 2.5 hours to complete all calculations. So, for 3 years it will take roughly one work day of tying up my computer to just compile data that will then require several days of calculation/manipulation.
Question(s): Is there a way to speed this up to a reasonable amount of time (I'd even take 30 minutes at this point)? Or, is Excel simply the wrong tool to be using for this amount of data? Do I need a better machine to run these calculations? I am currently using a Dell XT3 with 2.5 Ghz i5 quad core processor.

I have this example array:
A1
B1
C1
D1
A2
B2
B3
C3
D4
C5
D5
E5
...along with this example table:
.12345
A
B
C
D
E
In my table, I want to notate every occurence of A=1,A=2,B=1, etc; by placing an "X" in the correct cell. So, the table should look like this:
.12345
AXX
BXXX
CXXX
DXXX
EX
I cannot figure out the formula. I've tried this:
=If(VLOOKUP($L6,$I$6:$J$15,2,False)=M$5,"X"," ")
....but it seems to only return the first value found, and not all occurences.

I'm trying to use VBA to do some matrix processing. I have successfully done matrix processing in the spreadsheet, but I'm looking to port the logic into VBA to more easily reuse central formulas and reduce the amount of code in the spreadsheet.
The function shown below works. I had to hack around the variable declarations to eliminate processing/compile errors but it seems to function (no pun intended).
While debugging I noticed that this function would seem to get called 4 times. I do have other modules running, although I don't think any other modules are affecting this.
After some input from shg, I updated the variable declarations, but I'm getting an "Overflow" error reported. Sometimes (not always) a divide by zero also pops up. I do have the Msgbox for errors at the end, I haven't tried removing that part to see if the error reporting vanishes. I'm not sure 'hiding' error alerts is the best thing to do anyway...

I have tried to find information on this subject, but it seems diifficult to find exactly what I am looking for. I have provided a test example of the operation that I would like to acheive. The first example (Method 1) works well enough but would require defining more detailed functions beyond the scope of average. This would probably be ok, but more importantly, I would like to source particular arrays in this manner for other tasks beyond averages and even standard deviation and am not quite sure how this can be done. In an attempt to describe the situation, I have provided a second example (Method 2). In this example, I am trying to take the average of the jth column array to create an array of averages. I am not sure if I am incorrectly setting up the matrix, if the functions don't perform this way in the matrix, or if this is simply not possible.
Sub test()
a = 5
b = 5
Redim X(1 To a, 1 To b) As Double
'Assumes there is a matrix of values [a x b] drawn from worksheet
For j = 1 To b
For i = 1 To a
X(i, j) = Cells(i, j)
Next
Next
'----METHOD 1---------------------------------------------
'I know this way works using average as an example, but...
Redim AverageX(1 To a, 1 To b) As Double.......................

I have made a function (udf), called linjenr. It's input is an n by n matrix, and it returns a n by 2 matrix. This works fine in the worksheet. However, when I'm trying to use this function (udf) in a sub it fails, i.e. I get the error "object does'nt support this property or method". How do I use an own made function that returns an array in a sub macro? (ctrl shift + enter..)
Sub linjegenerator()
Dim nodematrise As Variant
Dim antlinjer As Integer
nodematrise = Range("F6:T20")
antlinjer = WorksheetFunction.Sum(nodematrise) / 2
If antlinjer < 3 Then
MsgBox "This is not a network. Minimum 3 lines."
ElseIf antlinjer > 2 Then
If antlinjer = 3 Then
'Range("F25:G27") = linjenr(nodematrise)
ElseIf antlinjer = 4 Then
'Range("F25:G28") = linjenr(nodematrise)
ElseIf antlinjer = 9 Then
Range("F25:G33") = WorksheetFunction.linjenr(nodematrise)
End If
End If
'antlinjer = WorksheetFunction.Sum(nodearray) / 2
MsgBox "Antall linjer = " & antlinjer

I have a 10 x 15 matrix named "Range1"
I have named the range of Column headings in that matrix as "Weight", and the range of Row headings as "Height". And then all the matrix cells contain some values.
Now I need to find the value from intersection of height and weight (please see the attached excel file)
Attention: I need to use excel VBA code to do the trick. (Not Worksheet formula using for example INDEX and MATCH)

In the attached sample file, one can see the setup of my data. I'm trying to reference the row number of a certain cell in a matrix with many cells of the same value. I have different Headers of each row, which should make it possible to use INDEX, MATCH or VLOOKUP. but i don't seem to be able to get it right.
Description.I need to return the "class" och each of the capability elements, i.e. If the capability in "Soups" is marked ("X"), at class 3, i need the integer "3" to be shown here.

I'm trying to set up a dependent cell (B) based on what is in the independent cell (A)
If A is blank, B should be blank
If A has any value other than X, B should display a set string Y
If A contains X, B should contain a drop down list with a range of choices.
I've tried setting it up as a dependent validation cell and I've tried using OFFSET, but the best I can do is to get three different drop down lists to populate cell B. One with only string Y, one with only a blank, and one with the range of choices. The problem is in the first two cases above, I want the cell to fill automatically with either blank or string Y -- I don't want them to just be drop down options, with the cell displaying the last value that was input.

I have created the following attachment to illustrate my problem. I have a square matrix -- say a 10x10 matrix (with data in B2:K11, and column headings on row 1, row headings on column A). I would like to get the sum of products of two columns in the result section below -- cells B14:K23, based on the position of the formula.
For example, cell B14 is the 1,1 item of the matrix so I would like to get the sumproduct of B2:B11 and B2:B11 (or SUMSQ(B2:B11) in this case); alternatively cell I16 is element 8,3 in the matrix so I need to get sumproduct of I4:I11 and D4:D11.
I tried the following formula using the OFFSET function (for cell B14 which is then copy/pasted throughout B14:K23)

Here is how my spreadsheet is set-up. This is unfortunately not something I can change :
- I have a list of products A to Z, starting in A2
- I have email addresses in row 1, starting in B1 up to Z99
- I have a matrix with 4 possible values in B2 to Z99. The values are either "L", "C", "I" or blank.
Here is what I am trying to do :
I would like to have a macro created for each product (column A) to send emails to those indicated in the matrix.
When the email is identified with "L" in the matrix for particular product, this email should be in the To:, when "C" or "I" it should go to CC:

In 'MAIN REPORT' there are thousands of columns of data, of which the important columns are 'Factory No.' and 'Row No' and 'Quantity'.
Each factory has its own worksheet as well.
In each of those factory sheets there is a 15x65 grid for each of the 65 rows that are mentioned in MAIN REPORT.
I have created and IF statement that checks if there is any data in 'Quantity row' and if there is it enters a "1" in the that cell of the virtual Factory grid.
This is the formula:
=IF('MAIN REPORT'!I2="","",1)
However, this simply checks that data while there is only 1 quantity for each row of each house.
Sometimes there will be different quantities (for diff. products), and I need a formula/macro that checks the line no. column and then,
If there are 5 items in row 7 for example then it will place five "1"'s in the first five cells of row seven in the corresponding factory sheet.

I'm trying to use an array to carry out string function on a range of excel cells.
Here is the code I am using
Dim arrXl As Variant
arrXl = ws.Range("F1:F" & ws.Range("D1").End(xlDown).Row)
For i = LBound(arrXl) To UBound(arrXl)
MsgBox (LBound(arrXl))
'If 1st char is different from 3rd char then remove all of string after 1st char
If Left(arrXl(i), 1) <> Mid(arrXl(i), 3, 1) Then
arrXl(i) = Left(arrXl(i), 1)
End If
'If 1st char is different from 7th char then delete string after 5th char
If Left(arrXl(i), 1) <> Mid(arrXl(i), 7, 1) Then
arrXl(i) = Left(arrXl(i), 5)
End If
The lbound function returns the value of 1 as the lower bound, I do not have "Option base 1" set so I was expecting the lbound value to be 0. The first 2 cells in the F column are blank so this may have something to do with it, I am unsure if cells in excel can be null if they can be null one cell may be null and the other may be a zero length string but I am unsure about this.
The ubound function returns a value of 487.
The code breaks when I try to access an element in the array so it breaks on the line:
If Left(arrXl(i), 1) <> Mid(arrXl(i), 3, 1) Then
and returns the "Subscript out of range" error message.

wish to write an VB macro in Excel (2003) that populates a 6 row by 10 column matrix (for a 3 D graph) by inserting values from matrix row column headers in cells in another worksheet and using goal seek to derive a value which will be pasted in the respective cell in the 6X10 matrix
Specific example: Matrix (Row Headers A2 to A7, Column Headers B1 to K1, Cell values are in B2 to K7). Please note row and column headers are numerical values since this is for a 3D graph
Macro to be written
Pick a value (numerical) from row header A3 in Sheet A and paste it in cell B6 in another sheet (Sheet B). Pick anothet value (numerical) from column header D1 in Sheet A and paste it in cell B7 in Sheet B.
Run a goal seek scenario such that cell S10 in sheet B is equal to 50 by changing cell G8 in Sheet B
Copy the value chosen/optimised by Goal Seek from cell G8 in Sheet B and paste it in Cell D3 (which is the relevant cell for the values for intersection of headers A3 and D1) in Sheet A
Macro should populate all cells in the matrix in Sheet A (matrix cells to be populated are B2 to K7) in a similar fashion
The macro should be locked in to the cells which are either being copied from or pasted into so that it still references them even if new columns or rows are inserted.

I'm only starting to get to grips with arrays. I have what I consider to be a lot of data that I need to 'cut' into separate workbooks. I have written some code that does this by simply looping through each line, 250k+, checking against a variable and copying the row into a separate sheet. This took longer than it would have doing it manually. It was suggested to me that I use arrays to speed up the process. I have managed to store the test data into an array but am struggling to find a way to loop through and pull out an entire 'row' from the array based on a variable. I have looked for 2 days in various places to find some way to loop through the data held in the array, but to no avail.
That code will appear here from about 8am GMT tomorrow. I know that once I've cracked this I'm on the road to some very significant time saving and comprehensive report writing.

If the issue is not immediately clear:
If I select, for example, columns B:E and group (Data -> group and outline -> group). These can be hidden/unhidden easily with the line and + button created in the process. A similar set of columns (e.g. P:S) will behave in exactly the same way. If I have grouped columns B:E however and then try to group F:H, I end up with one large group spanning B:H.
If it is possible to create these 'separate' or 'independent' adjacent groups, I'd love to know how; if not, I'd be interested to know if anyone else has found this irritating

Example:
Name Replied?
Bob N
Brian Y
Robyn N
Rachel Y
From the table above if I test for "N" I'd like the formula to return a list
of names, in this case Bob and Robyn.

How can I make the files path independent. Lets say I have 6 workbooks, one of them having macro that connects all the six books. While working on my pc, I entered the file locations by myself. The macro runs fine.
Now I have to send the files to someone and would not like them to add their download directory at most places in the code. I want that after downloading, they have to only open the main file and press the button to run macro. How should I do that.
Right now am using this approach:-
sub main{
str 1file;
set 1file = Workbooks.Open ("c:/downloads...../1stfile.xls")
and similar code for calling other files.

I have two spreadsheets which carry the same information in three cells. Instead of just placing a link, =B2 etc., I would like to have the cells linked to each other through code.
For the one sheet I can use this with no problem, but as soon as I place this worksheet change event in the other sheet but reverse the cells references Excel gets unhappy.
Code:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim rng As Range
Set rng = Target.Parent.Range("B2, M2, N2")
[Code]....
Any proper way to update a cell no matter which spreadsheet the change takes place?
Sheet1 >> change is made to cell B2 and that same value is applied to Sheet cell C4.
