Hi
I try to get the difference from two columns in a matrix... The function should be similar like the PREVIOUS function for rows... But instead of rows, I need the difference between columns... It's seams easy, but I already tried so many ways... no luck... its seems I need some custom code, but i have no idea hot to use achieve the result with custom code...
Here is an example:
The first month difference value is zero, because there are no values to compare.
The second month difference (= difference november) is built by month 1 amount and month 2 amount (amount november - amount october ) and so on...
Thanks for any help!
