WebIdea - Block Matrix Multiplication The idea behind Strassen’s algorithm is in the formulation of matrix multiplication as a recursive problem. We rst cover a variant of the naive algorithm, formulated in terms of block matrices, and then parallelize it. Assume A;B 2Rn n and C = AB, where n is a power of two.2 We write A and B as block ...

Web15 dec. 2024 · Steps of Strassen’s matrix multiplication: Divide the matrices A and B into smaller submatrices of the size n/2xn/2. Using the formula of scalar additions and subtractions compute smaller matrices of size n/2. Recursively compute the seven matrix products Pi=AiBi for i=1,2,…7. Now compute the r,s,t,u submatrices by just adding the … WebSTRASSEN’S MULTIPLICATION MATRIX. ... For this, we need to call the function Strassen recursively. The base case is when the matrix is of dimension 1 x 1 and the product of two elements is returned.
