本程序是用十字链表来存储矩阵并实现两个矩阵的相乘-this procedure is used to store Chain Cross Matrix and achieve the matrix multiplication 2

采用十字链表表示稀疏矩阵，并实现矩阵的加法运算-Cross-linked with that sparse matrix, and matrix addition operations to achieve

本代码是根据数据结构的只是，采用C语言编译代码，用十字链表实现稀疏矩阵相加-This code is based on data structure only, the use of C language compiled code, with the sum of cross-linked to achieve sparse matrix
