给定n个矩阵A1，A2，…，An，其中，Ai与Aj+1是可乘的，i=1，2，…，n-1。

确定矩阵连乘的运算次序，使计算这n个矩阵的连乘积A1A2…An时总的元素乘法次数达到最少。-Given n matrices A1, A2, ..., An, which, Ai and Aj+1 is multiplicative, i = 1,2, ..., n-1. OK matrixcontinuallymultiply order of operations, the computation of these n matrices even when the product A1A2 ... An element of the total number of multiplications to a minimum.
