S-matrix algorithm
WebThe current best algorithm for matrix multiplication O(n2:373) was developed by Stanford’s own Virginia Williams[5]. Idea - 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, Because matrix multiplication is such a central operation in many numerical algorithms, much work has been invested in making matrix multiplication algorithms efficient. Applications of matrix multiplication in computational problems are found in many fields including scientific computing and pattern recognition and in seemingly unrelated problems such as counting the paths through a graph. Many different algorithms have been designed for multiplying matrices on different types …

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… WebDec 15, 2024 · Steps of Strassen’s matrix multiplication: Divide the matrices A and B into smaller submatrices of the size n/2xn/2.
