计算机系统结构中，利用随机函数产生出两个随机矩阵，计算两个矩阵相乘。在此过程中，记录下两个矩阵相乘之前之后的两个系统时间，求出时间差。绘制出矩阵维数和时间的坐标图。-Computer system architecture, the use of random function to produce two random matrices, calculated by multiplying the two matrices. In this process, the record before and after the two matrix multiplication time of the two systems, find the time difference. Draw the matrix dimension and time coordinates map.
