说明：  利用哈夫曼编码进行信息通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。要求写一个哈夫曼的编译 码系统来实施通讯。入 都由系统直接提示完成。第二个矩阵的输入也是同样的道理。系统还支持矩阵的相加以及相减算法，只是这是系统附带的功能，而主要的功能是实现矩阵的相乘算法，所以相加和相减的算法是在矩阵相乘的基础上设计的
(Use Huffman encoding of information and communication can greatly improve channel utilization, shorten the transmission time information, reducing transmission costs. Asked to write a Huffman encoding and decoding system to the implementation of communications. Directly prompted by the system into complete. The second input matrix is the same reason. System also supports the matrix of the sum and subtraction algorithm, but this is incidental to the functions of the system, and the main function is to realize matrix multiplication algorithm, so add and subtract the algorithm is in the matrix multiplication based on the design of)
