The naive matrix multiplication algorithm contains three nested loops. For each iteration of the outer loop, the total number of the runs in the inner loops would be equivalent to the length of the matrix. Here, integer operations take time. In general, if the length of the matrix is , the total time complexity would ...

In linear algebra, the Strassen algorithm, named after Volker Strassen, is an algorithm for matrix multiplication. It is faster than the standard matrix multiplication algorithm for large matrices, with a better asymptotic complexity, although the naive algorithm is often better for smaller matrices. The Strassen algorithm is slower than the fastest known algorithms for extremely large matrices, but such galactic algorithms are not useful in practice, as they are much slower for matrices of pr… WebThe current best algorithm for matrix multiplication O(n2:373) was developed by Stanford’s own Virginia Williams[5].
