There are some procedures: Divide a matrix of order of 2*2 recursively till we get the matrix of 2*2. Use the previous set of formulas to carry out 2*2 matrix multiplication. In this eight multiplication and four additions, subtraction are performed. 2020-03-30 · Addition and Subtraction of two matrices takes O (N 2) time. So time complexity can be written as. T (N) = 7T (N/2) + O (N 2 ) From Master's Theorem, time complexity of above method is O (N Log7) which is approximately O (N 2.8074 ) Generally Strassen’s Method is not preferred for practical applications for following reasons.

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.

For example, consider two 4 x 4 Strassen’s Algorithm for Matrix Multiplication. Step 1: Take three matrices to suppose A, B, C where C is the resultant matrix and A and B are Matrix which is to be multiplied using Strassen’s Method. Step 2: Divide A, B, C Matrix into four (n/2)×(n/2) matrices and take the first part of each as shown below However, Strassen (1969) discovered how to multiply two matrices in S(n)=7·7^(lgn)-6·4^(lgn) (2) scalar operations, where lg is the logarithm to base 2, which is less than M(n) for n>654. For n a power of two (n=2^k), the two parts of (2) can be written Find Complete Code at GeeksforGeeks Article: http://www.geeksforgeeks.org/strassens-matrix-multiplication/This video is contributed by Harshit VermaPlease Li Group the blocks that comes from the same M sub-matrix.
