A                    = rand(x, y, z);
[maxValue, maxIndex] = max(A(:));
[ix, iy, iz]         = ind2sub([x, y, z], maxIndex);
[EDITED] Here "A" was created only as test data only. If you have the array already, you need the size() command to obtain the dimensions:
[maxValue, maxIndex] = max(A(:));
[ix, iy, iz]         = ind2sub(size(A), maxIndex);
