Nice, never heard of, but how does the case with zeros work? In the example with zeros, C has zeros and then they do some random operations (?) on the initial matrix to get rid of them. That sounds bad. Rather, if this is really O(n^3), this algorithm should be called first and if there happens to be a zero case, stop it and do the O(n^4) routine.
