[r, c] = find(A==min(A, [], 'all');

Note: this was specifically coded to be able to find multiple copies if the min is duplicated. If the min is unique then
[~, linearidx] = min(A(:));
[r,c] = ind2sub(size(A), linearidx);
This takes more lines but less processing time, as it does not need to scan the array twice.
