稀疏矩阵是指那些多数元素为零的矩阵。利用“稀疏”特点进行存储和计算可以大大节省存储空间，提高计算效率。实现一个能进行稀疏矩阵基本运算的运算器。

基本要求为：

以“带行逻辑连接信息”的三元组顺序表表示稀疏矩阵，实现两个矩阵相加、相减和相乘的运算。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 is ​ ​ a matrix that most elements are zero. " Sparse"　characteristics of the storage and computing can greatly reduce the storage space and improve computational efficiency. One can achieve for basic computing sparse matrix. Basic requirements: " OK logical connection information"　triplet sequence table sparse matrix, two matrix addition, subtraction and multiplication operations. Sparse matrix input form triple in the result of the operation of the matrix in an array of places usually listed.
