For the first challenge (Matrix Multiplication using Strassen's Algorithm) of Phase 2 of the 2009 Intel Threading Challenge I implemented Strassen's algorithm in Cilk++. I built versions that use both GotoBLAS and MKL to implement the base case of the recursion. I measured an effective ...
Figure 1 Matrix Multiplication 假如在矩阵 A 和矩阵 B 中, m=p=n=N ,那么完成 C=AB 需要多少次乘法呢? 对于每一个行向量 r ,总共有 N 行; 对于每一个列向量 c ,总共有 N 列; 计算它们的内积,总共有 N 次乘法计算。 综合可以看出,矩阵乘法的算法复杂度是:Θ(N3)。 二、Strassen算法 那么有没有...

This is a C++ Program to implement Strassen’s algorithm for matrix multiplication. In the mathematical discipline of linear algebra, the Strassen algorithm, named after Volker Strassen, is an algorithm used for matrix multiplication. It is faster than the standard matrix multiplication algorithm and ...

C#,数值计算,矩阵相乘的斯特拉森(Strassen’s Matrix Multiplication)分治算法与源代码 矩阵乘法是机器学习中最基本的运算之一,对其进行优化是多种优化的关键。通常,将两个大小为N X N的矩阵相乘需要N^3次运算。从那以后,我们在更好、更聪明的矩阵乘法算法方面取得了长足的进步。沃尔克·斯特拉森于1969年首次发表了他...
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. ...
