I have a matrix like
A=[3 2 1;3 1 2;2 3 1];
I want to find the position of 2 in each row
I need
1 2
2 3
3 1
which indicates that at first row it is in second column, at second row it is is in third column and at third row it is in first column,
Thanks

A = [3 2 1;3 1 2;2 3 1];
[r, c] = find(A == 2);
output = [r, c]
