Matrix To Return Risk Rating - Array Returns Opposite Result
Nov 20, 2013
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.
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.
I have a list of employees who each have a performance rating (very top, consistent, etc). Each employee is also either above the midpoint of a salary range or below (which is represented by a separate column with 'Yes' for above and 'No' for below).
What I am trying to do is apply a separate set of %'s for each group of employees. So, for the employees who are below, I want to return 10% and 8% for each respective rating, but for those employees who are above, I want to return 8% and 6%. (for example).
I need to multiply an array of logical results ( returned as {1,0,0,0,1,0 et.}) with a text array (a reference column) and return the text in the reference column in case the value in the logical array is 1.
I have a table with subtotals that I need to find the largest value for the subtotal results and then return the cell contents for the corresponding row.
I have attempted to use the hlookup function, but keep getting a #ref error (probably because I am just not that familiar with the entire formula requirements).
I attempted to nest in the 'largest' function to the lookup function, but have so far been stymied....
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"?
I've been searching the forums and web trying to figure out how to extract a text value from a 3D array result, to no avail or well beyond my understanding.
I've attached a file which shows an abbreviated version of the search (from the original 49 col x 400 row, which shows the name to date array which can return a sum.
What I'm looking to do is identify within this array result if there has been a text entry, and return the text as opposed to a sum of the remaining values. This is essentially a double check to make certain that there aren't hours scheduled when other events such as vac/loa/etc are also booked.
I want to display the path result from a Floyd Algorithm matrix output..
You can download the excel file here : http://ifile.it/lw4tgic It consists of 1044 nodes, and we need to find the path between 2 nodes for ALL pairs..
Now, to find the path between 2 nodes, we need to : 1. Find the resulting cell of corresponding 2 nodes (y to x = z) 2. Update the path with that value (y z x) 3. For all the direct pairs in the current path (yz, zx), find the resulting cell 4. If destination (x) not the same with result (z) then repeat step 1 for that pairs. 5. repeat until x = z for all pairs.
Maybe it's better if i use an example.... we'll use T01 to E78 as an example
T01-E78 = if you look in the table, y (vertical) = T01, x (horizontal) = E78 z (result) = E77, so
T01-E78 = E77, so path = T01-E77-E78
check if result of T01-E77 = E77 (x = z?)...........................
I have a two different formulas the return a numbered result(PO Number) in the same column. I then vlookup both of them with the same formula into a pivot table, one returns the result one doesn't. format appears to be the same.
Code: =VLOOKUP((LEFT(C4,6)),'Data from 7500'!$B$16:$G$195,6,TRUE)
And it works great, except that the data returned is off by one row. For example, the correct value for the sample name in B107 is located in G107, but the formula returns the value in cell G106. I've tried changing the TRUE to FALSE and that returns #N/A.
I have created a table in excel, and it has a very simple sum totals. When i include all cells in the table the total becomes 0. When I exclude a cell in the table, the total shows. I have deleted the row and re inserted another one and copied the cell content from above that was not having a problem,
In the attached file I used =MATCH(TRUE,INDEX($B$2:$B$10="",0)) to retrieve the location of the first empty cell.
When using the "Evaluate Formula" tool, it is clear that the position in the array created by the INDEX function is the 6th. Nevertheless, the final outcome is 9, being the last cell in range.
I have a worksheet called "Raw Data" where in columns J, I and G contain values. I would like to write a formula whereby if all 3 conditions are met, it will count the number of values found in column C.
I've tried to write an IF statement but it just returns FALSE, despite the result being true. Need the right combination of IF/AND statements that would do this?
=IF(AND('Raw Data'!$J:$J="Maintenance",'Raw Data'!$I:$I="Open",'Raw Data'!$G:$G="1-2008"),COUNT('Raw Data'!$C:$C)). I've tried to attach the workbook, but there's a problem with uploading attachments I think. Sorry if my explanation is unclear.
I have a simple formula subtracting one cell from another using =SUM(XX,-XX). When I click on fx and bring up the function arguments box, the formula result is displayed correctly in that box. However, the cell containing the formula will only display a zero. I have tried reformatting the cells to no avail. I have also tried getting a result using =XX-XX and that does not work either.
I have a three or four letter abbreviation of a last name in A1. Column C contains a list of Last Names; column D contains a list of corresponding First Names; and column E contains a formula concantenating the First Names and Last Names from columns C & D.
I have the following formula in B1:
=VLOOKUP(A1,C1:E44,3,1)
I am attempting to match up the three or four letter abbreviation with the concatenated list to return the full name (First and Last) in cell B1, however, I'm not getting the desire result. I keep getting the name in the row just above the name I want.
I have discovered a strange thing about excel and it is driving me mad and ruining my project.
Basically, If i enter the number 97.4 into cell A1 and then 97.165 into cell B1 and then enter the formula =A1-B1 into cell C1 i get the answer 0.235. Which is correct.
However, when you increase the number of decimal places to 30 the answer that is returned is 0.234999999999999000000000000000.
This calculation result seem to fluctuate wildly depending on the primary numbers in cells a1 and b1. Very rarely have i seen the full 30 decimal places without a bizarre result like this.
Maybe it has been too many years since i was at school and that i am confused with my numbers and that there is a real easy answer to why this result is returned.
As i said it is ruining my project that i am working on. Can anyone help? Why does excel do this? Is there a way to stop this happening? My project relies on this answer to be correct. Is there a way to force excel to stop doing this?
I'm compiling a list of names on a separate tab from a column that only lists the names sporadically. Problem: In the formula, the IF provides a TRUE, the row function, and consequently, the INDEX function (when I hit F9) provides the correct "name" and row number, but when I hit return, it provides the text 4 cells beneath what it should.
I need a formula to count cells based on the date, so that I can have a blank cell when the answer is 0. I am adding values cumulative and future cells need to be blank because I have a graph that has a trend line and I don't want the trend line to fall off at the end. I also don't want to have to go back to this every month and update it.
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'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 2 tables, 1 beneath the other - table 1 columns represent date ranges and their values. Columns and their data are alternating color coding. Table 2 references, by means of array formula, this data - IS it possible to include the font color as a result?
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
I don't know if this is vba, because my sheet has no macros in it. I have a reference cell and an array. The array mentions the same value as the reference cell does several times in one column. In the other column, however, are individual values. I would like to find a way so that when you change the reference cell, the values in the "Return Cells" correspond accordingly. See attachment
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)
