编写实现C=A+B操作的函数。其中，矩阵A、矩阵B和矩阵C均采用压缩存储方式存储，矩阵元素均为int类型。并设计一个测试主函数，要求按矩阵方式输出矩阵C的数值。设矩阵A和矩阵B为如下所示的矩阵：

A=[█(1 2 3@2 4 5@3 5 6)] B=[█(10 20 30@20 40 50@30 50 60)]

-Prepared to achieve C = function A+B operation. Among them, the matrix A, the matrix B and C matrices are stored in compressed storage, the matrix elements are of type int. The main function and design a test that requires the matrix output matrix C values. Let matrix A and matrix B is a matrix as follows: A = [█ (1 2 3 @ 2 4 5 @ 3 5 6)] B = [█ (10 20 30 @ 20 40 50 @ 30 50 60)]
