Strassen's algorithm formula
Webapproach for this problem is possible. Let us recall Strassen’s algorithm [24] (see Algorithm 3). Strassen’s key idea is to multiply 2 2 matrices using 7 scalar multiplies instead of 8. Because n n matrices can be divided into quadrants, Strassen’s idea applies recursively. Each of the seven quadrant multiplications is computed re- Web26 Nov 2012 · I wrote two Matrix Multiplications programs in C++: Regular MM (source), and Strassen's MM (source), both of which operate on square matrices of sizes 2^k x 2^k (in other words, square matrices of even size). Results are just terrible. For 1024 x 1024 matrix, Regular MM takes 46.381 sec, while Strassen's MM takes 1484.303 sec ( 25 minutes ...

Strassen's algorithm needs to be compared to the "naive" way of doing the matrix multiplication that would require 8 instead of 7 multiplications of sub-blocks. This would then give rise to the complexity one expects from the standard approach: O ( 8 log 2 n ) = O ( N log 2 8 ) = O ( N 3 ) {\displaystyle O(8^{\log … See more In linear algebra, the Strassen algorithm, named after Volker Strassen, is an algorithm for matrix multiplication.
