Return Inverse Matrix Of Large Matrix
Aug 22, 2008Using 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"?
Creating A Scenario Matrix
Mar 9, 2007Creating a Scenario Matrix. I am using Excel XP. Simplifying the problem, I have a formula;
Cell A1 has X,
Cell A2 has Y
Cell A3 has Z
X * Y = Z
I want to find the answers when X is between 1 and 5 and Y is between 1 and 5. I want this to be in a matrix so I want the answers:
1 2 3 4 5
1
2
3
4
5
I cannot use Scenario Manager; it would record the answers on the pivot table or summary which is what I want BUT I would have to type every combination (1,1), (1,2) etc!
Creating And Using Port Distance Matrix?
Jul 28, 2014I have 1551 rows of port distances, as shown below.
From To Distance
Abu Al BukhooshDalian 6097
Abu Dhabi Jamnagar929
Ain Sukhna Gibraltar2026
Akpo Field Inchon9755
I have a list of 206 ports. I want to build a matrix of Port distances with the names of the ports (206 names) on the first row and column and the distance from each port to every other port. I understand that the 1551 rows of data that I have is not sufficient, but those are he only significant ones. For the missing records I would like to put "zero" in the matrix.
Also, Once the matrix is built, how can I use it to find the port pair distance when the user inputs two port (From port and To port)?
Counting Formulas And Creating A Matrix
Feb 16, 2009I have the following used formula to count how many occurances there are of a particular piece of text in a column:
=SUM(IF(range="text",1,0))
e.g. {=SUM(IF(K6:K16="H",1,0))}
I have repeated this formula for an adjacent column
e.g. {=SUM(IF(L6:L16="M",1,0))}
I need to find a way of counting number of occurances in these two columns (K and L) when text "H" and "M" are present in the same row.
To further complicate matters (well for me anyway) the text "H" and "M" care chosen from a list of options in the K and L columns.
What i ultimatly want to do is create a matrix to compare how many times all possble occurances of the various options listed in both columns are present in the same row in the spreadsheet.
Creating Matrix With Variable Size

Correlation Matrix In VBA
Jan 16, 2006I have code to create a correlation matrix (NxN, where N is the number of columns). This is done by selecting an area that is NxN, entering the function and range, then hitting ctrl +shift + enter (array formula).
However, I want to convert this to accept VBA arrays, rather than a data range, and give the output in form of an array as well.
VB:
Function CorrmatK(dataRange As Object) As Variant
On Error Goto 20
Dim r As Integer, n As Integer, rr As Integer, i As Integer, j As Integer, k As Integer, doit As Integer
Dim x() As Variant, mc() As Double, ss() As Double, m() As Double, ob As Object

Moving In A Matrix
May 23, 2007I have a matrix A with 12 rows and 10 columns. My problem is if in the cell(i,j) there is data then the same data should appear in a similar matrix B, but in a cell which is 15 cells behind the cell(i,j).
That is it should start counting upwards from cell (i,j) in B and once it reaches the top of the matrix it should continue counting from the bottom of the immediate left column and go up. When it reaches the 15 cell from cell(i,j) in b, it should print there the value that was in cell(i,j) of A.

Correlation Matrix
Jul 25, 2006I wasn't able to attach the file because it was too big, but you can download it from here www.easygcc.com/correl.rar. On the sheet called " Correlation" there is matrix, I am baiscally trying to fill in the correlation formula into every cell so the matrix is filled out. The data for the correlation calculation comes from the sheet called "Tech Data". I have filled in the correlation formula into a few of the cells as an example, but I don't want to continue doing this manually but rather have a macro do it for me. Otherwise this will take for ever. My macro is also a part of the file, if you would liek to look at it and maybe fix what I already have.
View 4 Replies View RelatedMatrix Lookup
Dec 4, 2006I have a 5 x 5 matrix. When values are entered in 2 cell there needs to be a matrix lookup and the corresponding value needs to be entered into the 3 cell. Example :
- A B C D E
V 1 2 2 3 3
W 2 2 3 3 3
X 2 3 3 4 3
Y 3 3 4 4 5
Z 3 3 4 5 5
So if X and D are entered into the 2 cells the 3rd cell should show 4.

Finding Data From A Matrix
Feb 17, 2009On my example sheet it shows how many cables and how the cable length per job. What i need is for the hour/job column to be populated from the Hours sheet by matching the column and row. e.g 4 cables at 40 metres would give me cell D7 (27.89), as 25 metres would be no good - so rounding up would be required.

Feb 12, 2013I'm struggling to find the right Excel functions to fill up a block matrix. Here are all the details of my problem.
I have a list of firms and relative products. Each firm can produce either 1, or 2 or 3 different products, for instance
firm A produces product x
firm B produces products y and z
firm C produces product j
firm D produces products k, h and q
Suppose the data appear on a sheet in column order, that is, one column for the firms and one for the products with a space between A, B, C and D when one firm is a multi-product producer. I need to create a 0-1 block matrix in Excel setting 1 when the product is produced by the same firm and 0 otherwise, i.e. for the above example
x y z j k h q
------------

0 1 1 0 0 0 0
0 1 1 0 0 0 0
0 0 0 1 0 0 0
0 0 0 0 1 1 1
0 0 0 0 1 1 1
0 0 0 0 1 1 1
I can do this in VBA but not in Excel, and unfortunately I need to provide an Excel solution.

View 14 Replies View RelatedMatrix To Single Column
Jan 2, 2006I have an array of data with column headings and changeable row "item names"
in the left most column. The intersecting matrix of data contains quantity
values at the intersection cells of column and row headings. I need to
automatically reorganize the data as a list in a column with the row "Item
Names" at the left but and repeated as necessary but instead of the
additional columns of quantity values, I need to have this data listed in a
single vertical column along with an additional column with the original
column header that corresponds to the quantity value. I think there must be
some kind of lookup function to do this but I can't find the right way to do
it.
Turning Data Into Matrix?
Oct 18, 2011I have 2 lines with pairs and 3rd with corresponding values, nee to construct a matrix out of it with formulas
Example
Need to turn
AAABBDBCDCDC0.30.20.130.550.840.43
into
ABCDA11-0.31-0.21-0.13B0.311-0.551-0.84C0.20.5510.43D0.130.841-0.431
So the one that stands above in the initial file goes to the top line in the matrix. 2 line -> column in matrix. In case there is no match need to seek reverse in 1,2 and reflect as 1-VALUE in the matrix
