CRC校验，实现基本的CRC校验功能，当mask不同时，修改也相当方便(CRC checksum, CRC checksum to achieve the basic function, when the mask is not the same time, changes are also very convenient)

matlab关于直方图，均衡化，白平衡，匹配，边缘检测，图像变换的有关数字图像处理方面的几个程序代码。(matlab on histogram equalization, white balance, matching, edge detection, image transformation on several aspects of digital image processing code.)

说明：  基于MATLAB的“电力电子技术"仿真实验的研究 为了方便地对这些变流电路进行仿真， 采用了MATLAB的Simulink库。同时，还采用VISUAL BASIC语言将电力电子变流电路的波形与MATLAB 仿真界面进行链接，以便更简洁地、直观地，甚至是在无人指导的情况下，让学习者独立地完成电力电子 变流电路的仿真实验。 (MATLAB based on the &quot Power Electronics&quot simulation study in order to facilitate these changes to circuit simulation using the MATLAB-Simulink library. At the same time, the use of VISUAL BASIC language of power electronic converter circuits and the MATLAB simulation waveforms link interface for a more concise and intuitive manner, even in the absence of guidance to enable learners to complete the independent power electronic converter circuit simulation.)
