RFC1662 CRC-16 table generation and CRC checking. Implemented in embedded matlab with script to test and enable c/c++ code generation. Useful fo check against VHDL/Verilog and other embedded systems to help generate test vectors.

此程序为matlab函数，实现用结构相似性（SSIM）准则评价图像，与峰值性噪比的作用类似。(This program is a matlab function, and criteria for evaluation of structural similarity (SSIM) image acts like a peak-noise ratio.)

最大频率选择小波的实现的经典论文之一，非常有启发性(The realization of maximum frequency selective wavelets, one of the classic papers, very enlightening)

使用MATLAB创建GUI界面，对图像进行相关处理，例如：几何变换、滤波、加燥等。(Use MATLAB to create a GUI interface for image-related processing, such as: geometric transformations, filtering, plus dry and so on.)

matlab生成m序列的函数 原来那个效率太低，主要是因为实际应用并不需要生成太长的m序列，加入了需求长度，能有效减少运行时间。25级的移位寄存器，运行了一个小时都没有出来一周期，我仅仅需要三千bit而已。改进版：(matlab generate a function of the original m sequence that efficiency is too low, mainly because of the practical application does not require generation of long m sequences, joined the demand for length, can effectively reduce the running time. 25 of the shift register, run for an hour did not come out one cycle, I just need more than 3000 bit. Improved version:)
