Hello,
I have a 2D matrix, and I want to know the minimum and its indices. I normally use min(min(matrix)), and I found here that I can also use min(matrix(:)). But I couldn't find out how to also get the location of this found minimum?
Thanks in advance!

minMatrix = min(matrix(:));
[row,col] = find(matrix==minMatrix);

M=[4 5 6;2 1 4;1 0 5]
[min_val,idx]=min(M(:))
[row,col]=ind2sub(size(M),idx)
