Matrixmultiplikationsalgoritm - Matrix multiplication algorithm utformad av Volker Strassen 1969 och kallades ofta ”snabbmatrismultiplikation”. The goal of this paper was to look specifically at matrix multiplication and Algorithms for Large Matrix Multiplications : Assessment of Strassen's Algorithm. Only requires 7 multiplications (and 18 additions). Volker Strassen, 1969. – Typeset by FoilTEX –. 11.

Making Strassen Matrix Multiplication Safe Himeshi De Silva, John L. Gustafson, Weng-Fai Wong School of Computing, National University of Singapore Singapore Email: fhimeshi, john, wongwfg@comp.nus.edu.sg Abstract—Strassen’s recursive algorithm for matrix-matrix multiplication has seen slow adoption in practical applica- Strassen’s matrix multiplication. Let A and B be two nn matrices, that is, each having n rows and n columns.If C=AB, then the product matricx C will also have n rows and n columns. Strassen traded off one matrix multiplication for a constant number of matrix additions, thus got a lower asymptotic running time.

Strassen's matrix multiplication algorithm follows divide and conquer technique. In this algorithm the input matrices are divided into n/2 x n/2 sub matrices and then the recurrence relation is applied. Strassen’s fast matrix multiplication and minimizes communi-cation. The algorithm outperforms all known parallel matrix multiplication algorithms, classical and Strassen-based, both asymptotically and in practice.
