传统方法与Strassen算法相结合的矩阵相乘算法，可以求出任意两个偶数阶矩阵的乘积！本代码简单,精简，非常好！非常巧妙！没用到什么复杂的东西！经测试完全正确！-Strassen with traditional methods based on the combination of matrix multiplication algorithm, can be obtained even arbitrary two-matrix product! The code simple, concise, very good! Very clever! What sorts of complicated things! After testing entirely correct!
