1: define two two-dimensional array is used to store matrix
2: input/output: input with operation of two matrices, the output result
Add: 3: matrix determine whether two matrices can be combined, such as, calculating the sum of two matrices, and the result output
4, 5 by reduction condition with 3
6, the number of matrix and multiplication: enter the Numbers, matrix and the number of each product, as a result, the output
7: matrix transpose: calculate each matrix transpose, result output
