Find row and columns of matrix index in MATLAB

Question

I want to ask something, is there any way to get the row number and column number if I know the index number of a matrix? For example, I have A= 3x3 matrix, and I want to find the row and column for index number 5 on the matrix. The answer should be like this: rows=2 columns=2.

Thank you! Please help me out. I've been stuck on this for a while now. :(

Answer 1

Perhaps try ind2sub ?

IND = [3 4 5 6]
s = [3,3];
[I,J] = ind2sub(s,IND)

I =
     3     1     2     3

J =
     1     2     2     2
