I've got a data like this. Each file contains zero and some positive values or all zeros.
I want to find which matrix contains positive values.

If A is your matrix.
idx = A>0 ; % this gives indices of posittive values
idx = sign(A) % this gives sign of values in A
A(A>0) % this gives values in A which are greater than 0
