稀疏矩阵的运算，主要用于测试算法实现，矩阵由系统随机生成，由用户选择需要的操作，包括矩阵的加减乘运算，稀疏矩阵的输入形式采用“三元组”表示，而运算结果的矩阵则以通常的阵列形式列出。-Sparse matrix operations, mainly for testing algorithms, matrix randomly generated by the system, select the desired operation by the user, including matrix addition and subtraction, multiplication, sparse matrix input form a " triple" , said the results of the operation The usual array matrix Zeyi be listed.
