Matrix multiplication is the product of two matrices, which results in a single matrix. Visit BYJU’S to learn how to multiply two matrices, formulas, properties with many solved examples.
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. ...

The matrix pre-multiplication order convention can be described as placing parentheses in this way (shown below) to indicate the intention of a particular order in which an operation (e.g. a combination of transformations) is performed. Z=A∗B∗C∗D∗E=(((A∗B)∗C)∗D)∗EZ...
# Strassen's matrix multiplication algorithm.## Given two matrices A and B, start by padding them to be the same size, where# the number of rows and columns is a power of two. Then, it subdivides the# matrices into 2x2 block matrices, and uses a faster algorithm for multiplying# 2x...

We propose a divide-and-conquer strategy to discover hierarchical community structure, nonoverlapping within each level. Our algorithm is based on the highly efficient rank-2 symmetric nonnegative matrix factorization. We solve several implementation challenges to boost its efficiency on modern computer ar...
