Getting the position of the largest value in a matrix

Question

Say that I have the following matrix in MATLAB:

I=[2 1;4 5];

How can I retrieve the position of the largest element??

Answer 1

You can do as follows:

[value, location] = max(I(:));
[row,col] = ind2sub(size(I), location);

>> [row, col]                            

ans =

     2     2
