I have been trying to get this function to work but cant seem to get the correct result. What I am trying to accomplish is to Index Match Match a cell from the second table to the first table and evaluate the first set of coordinates, lets say (a,c) , with another set of coordinates (c,a). I will always be evaluating the inverse of each others coordinate. If all goes correctly, the two points in this example are -4 and 4. If the two coordiantes match eachothers inverse then True, otherwise False. I think I set up my function correctly but I cant seem to find the issue with it.
Try this formula:
I think you just mixed up your rows and columns. Also, you don’t need the first
INDEX, you can just refer to the cell
Example (note I changed one value just to make sure it is working):
If it is always a square matrix, and you don’t mind entering it as a single array formula, you could use
TRANSPOSE. Enter this in a 5 x 5 area and commit with ctrl+shift+enter:
