Submitted by Prerana Jain, on June 22, 2018 . By using our site, you Divide and Conquer Method. Strassen in 1969 which gives an overview that how we can find the multiplication of two 2*2 dimension matrix by the brute-force algorithm. Order of both of the matrices are n × n. We have discussed Strassen’s Algorithm here.However, let’s get again on what’s behind the divide and conquer approach and implement it. Here the dimensions of matrices must be a power of 2. I will use the I am also happy if you post some of your solutions with running times ☺If you know other languages, you could create a script for these. This is a program to compute product of two matrices using Strassen Multiplication algorithm. All Rights Reserved.
Don’t stop learning now. I focus on Python, Java and C++.I have implemented only the Strassen algorithm for this post.
The program output is also shown below. Here is the source code of the Java Program to Implement Strassen Matrix Multiplication Algorithm. If you wish to look at all Java Programming examples, go to
Consider two matrices A and B with 4x4 dimension each as shown below, The matrix multiplication of the above two matrices A and B is Matrix C, (N is a power of 2). In this article, we are going to discuss about the strassen matrix multiplication, formula of matrix multiplication and algorithms for strassen matrix multiplication. Strassen’s Matrix Multiplication Algorithm. The program should be able to accept any size of N N matrices.
Strassen’s method is similar to above simple divide and conquer method in the sense that this method also divide matrices to sub-matrices of size N/2 x N/2 as shown in the above diagram, but in Strassen’s method, the four sub-matrices of result are calculated using following formulae. Write a Java program to implement Strassen’s Matrix Multiplication Algorithm. /** Funtion to split parent matrix into child matrices **//** Funtion to join child matrices intp parent matrix **/ The Java program is successfully compiled and run on a Windows system.
As last time, I've added the scripts to a GIT repository, so feel free to test it on your machine. We have discussed Strassen’s Algorithm Attention reader! Please take a look at Wikipedia for a detailed explanation how this algorithm works. acknowledge that you have read and understood our
We use cookies to ensure you have the best browsing experience on our website. Before jumping to Strassen's algorithm, it is necessary that you should be familiar with matrix multiplication using the Divide and Conquer method.
This is a Java Program to Implement Strassen Matrix Multiplication Algorithm. The Java program is successfully compiled and run on a Windows system. The Strassen’s method of matrix multiplication is a typical divide and conquer algorithm. Here is the source code of the Java Program to Implement Strassen Matrix Multiplication Algorithm.
Strassen’s Matrix multiplication can be performed only on square matrices where n is a power of 2.
