WebApr 5, 2013 · This method gives the fastest result (matrix multiplication goes as O (n^3) and transpose as O (n^2) so doing the transpose is at least 1000x faster). The wiki method without blocking is also fast and does not need a buffer. The blocking method is slower. Another problem with blocking is it has to update the block several times.
