一个用ArrayList做的非常不错的矩阵相乘的程序。

实现矩阵连乘算法，求出最优值及一个最优解。-Even realize matrix multiplication algorithm, find the optimal value and an optimal solution.

用面向对象的方式来实现矩阵的加减乘法，必须有矩阵类和调用类和主类-Object-oriented approach to achieve matrix multiplication and subtraction, there must be a matrix class and call the class and master classes
