稀疏矩阵的元素值的范围为1~1000之间的整型数。利用随机函数按1 的非0元素概率生成这个矩阵，并将矩阵存入闭散列表中。并检验最后生成的非0元素的个数是否为1 -Sparse matrix elements of the scope of the value for 1 ~ 1000 between integer. The random functions with 1 of the 0 element probability generating the matrix, which clo

利用十字链表实现稀疏矩阵的存储、输出、相加、相乘等运算-The use of cross-linked list sparse matrix storage, output, added multiplications

大型稀疏矩阵求逆，采用通过U、L分解的方法求解-Large sparse matrix inversion, through the L, U decomposition
