WebbThe answer is the same for both questions here. Let's take the cell 1, 1 (first row, first column) of M. The number inside it after the operation M = A ∗ B is the sum of all the element-wise multiplications of the numbers in A, row 1, with the numbers in B, column 1. That is, in the cell i, j of M we have the sum of the element-wise ... WebbIf multiplication of two n× n matrices can be obtained in O(nα) operations, the least upper bound for αis called the exponent of matrix multiplication and is denoted by ω. A bound for ω <3 was found in 1968 by Strassen in his algorithm. He found that multiplication of two 2×2 matrices could be obtained in 7 multiplications in the ...
