中文说明： 计算机网络课程设计 基于Matlab实现CRC编码和解码；具有良好的人机交互界面，实现CRC和海明的编码和解码；同时具有错误提示功能，判定输入数据是否合法，不合法数据会弹出ErrorDiag 提醒用户更改输入；输出数据在输入更新完之后，自动刷新；
English Description：
The design of computer network course is based on MATLAB to realize CRC encoding and decoding; it has a good man-machine interface to realize CRC and Hamming encoding and decoding; at the same time, it has the error prompt function to determine whether the input data is legal or not, and the illegal data will pop up errordiag to remind users to change the input; the output data will be automatically refreshed after the input is updated;
