Hello.
I have a matrix M = 10x5. 10 representing the number of users and 5 the values for each user. This is taken out of the bigger matrix A = 161x161x10. 10 again being the same number of users as in the M matrix. The values from M are in A.
My main goal is to find the indexes (or ROW,COL) from the values from matrix M in matrix A. The problem is that because in M , I have duplicate values I can't find use the FIND function. Based on my research I did not found something helpful.
Do you think is possible to do this? Thank you!

[row,col]=find( reshape( ismember(M(:),A(:)) , size(M) ) );

@Matt J Thank you very much! I could not make it work with row and col but I am finding the indexes and then I will convert into row and column. The only problem is when the indexes are added to the cell they are added in ascending order which for my case is not the ideal case but I think I can sort it out somehow.
Thank you for the answers. If you have any more suggestions, I am happy to read them!
