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。-The input interface (graphical or text interface can be), to distinguish between addition, subtraction, multiplication, and transposition　be able to handle any input data and typical data processing errors (such as multiplication, when the first number of columns of a matrix is not equal to the second When a matrix of rows)　must be used as triple storage structure, can not use an array of other forms　output requirements in the form of a matrix output (ie 136 in the form of problem sets), when the first rows of a matrix is not equal to the first the number of rows of two matrices, the attention in the form of multiplication as the third output.
