Inverse Vlookup

May 16, 2007

Basically 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.

Fill Table From 4 Known Values. Inverse Of Extrapolating

Sep 24, 2008

From four known set values at the four corners of a table, how can I fill in the values in between? I.E. the inverse of extrapolating. I have a program within a programme that will do this, so i know its possible, but ideally i would like to be able to do it straight into a spreadsheet.

Excel 2003 :: Labeling Horizontal Axis Of XYScatter Chart With Math Division Inverse

Jan 16, 2013

We 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?

In One Cell: Calculate The "inverse Sum" Of A Column

Jan 12, 2010

I 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.

Return Inverse Matrix Of Large Matrix

Aug 22, 2008

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"?
