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"?

Excel 2003 :: Labeling Horizontal Axis Of XYScatter Chart With Math Division Inverse
Jan 16, 2013We make many graphs using XYscatter charts with lots of data points using Excel 2003 with the horizontal scale properly scaled as frequency. I have been asked to label that axis in some way as period (=1/frequency) without changing the scaling for the data plot. Is there a suitable way to do this? It would be OK to just change the axis numbers to 1/frequency computed from them automatically. Is Excel 2010 any easier for this?

Automate Build Of Design Matrix In MS Excel
Jun 15, 2014A typical Design Matrix is shown in the attached Workbook. There are two domains of Merged Cells that make up the Headings of the Matrix; FRs (Functional Requirements) and DPs (Design Parameters). Given a Hierarchical List of FRs specified by the User, the User would like Excel to bulild the Matrix Hierarchy of FRs automatically (going down the Worksheet). The DP Hierarchy is the same hierarchy, except transposed and reflected across the Worksheet. The attached Workbook has up to seven (7) levels, but the ability to go create up to 10 levels is desired.

Oct 16, 2013I have been using Excel to record the routine daily issue of items to different groups in a matrix layout, I use a different workbook for each month with worksheets for each group. The matrix takes the form of the item issued being the left hand column and the date issued the top row of the matrix, the quantity issued is recorded at the intersection. Each item can have a different quantity issued on different days. I'm using Excel 2011 for Mac but could use PC Excel 2010. Is there a way to convert the data held in this way to a list? What I'd like to achieve is a list showing the Item, the Quantities Issued and the the Issue dates

May 16, 2007Basically we have a "master" spreadsheet that people type in all day. During the day we have another team which send us a seperate " upload" spreadsheet inputs some of the cells for us, and I need to vlookup these values and ensure that all this information is input in.
Now a vlookup would be quite easy to do but I wont be able to use that as the cells would be full of Vlookups - and I would end up with a load of #N/A errors. The workbook is also shared and any macro would have to work with other users in the sheet.

In One Cell: Calculate The "inverse Sum" Of A Column
Jan 12, 2010I have 26 columns of data, and each column is 1500 rows long. At the bottom of each column, I'd like to calculate a "inverse sum" -- the "inverse sum" should be the sum of the inverse of each value in the column. It should not be the inverse of the sum of the column. In other words, a column with these 3 values:
2
4
4
Should result in an "inverse sum" of 1, namely one-half plus one-quarter plus one-quarter. It should not result in one-tenth, namely the inverse of the simple sum, or ten.
** I know ** how to do this by adding a "computational column" next to each "data column", and the summing the computational column. But I don't want to do this because it will double the number of columns to 52, and since I'm not the only user of this spreadsheet, I prefer to not start hiding columns.
So... is there a way -- in one cell at the bottom of each column -- to calculate the "inverse sum" of the column above? A CSE array formula would be fine, if it works.

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.

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.
