稀疏矩阵运算器，实现稀疏矩阵的加法、减法、乘法、和转置运算，有输入界面（图形或文字界面都可），能区分加法、减法、乘法和转置；能处理任意输入的典型数据和进行出错数据处理（例如乘法，当第一个矩阵的列数不等于第二个矩阵的行数时）；必须采用三元组作存储结构，不能采用数组等形式；输出要求用矩阵的形式输出（即习题集136页的形式），当第一个矩阵的行数不等于第二个矩阵的行数时，注意如第三个乘法的形式输出-Sparse matrix operations, which realizes the sparse matrix addition, subtraction, multiplication, and transpose operations, with input interface (graphical or text interface can be), to distinguish between addition, subtraction, multiplication, and transposition　can handle any typical data input and the error data processing (eg multiplication, when the first number of columns of a matrix is not equal to the second matrix when the number of rows)　must be used for the storage structure of the triple, you can not use an array of other forms　output requirements in the form of a matrix output (ie, page 136 in the form of problem sets), when the first rows of a matrix is not equal to the number of rows the second matrix, the attention as the third output in the form of multiplication
