使用matlab的GUI控件，编写的一个图像处理的界面，内容是 借鉴何凯明的去雾算法原理对受辐射的红外图像进行复原的过程。希望对大家有帮助。(Using matlab GUI controls, prepared by an image processing interface, the content is to learn to fog algorithm principle 何凯明 of infrared images were restored by the radiation process. Hope everyone has to help.)

多元统计分析过程下的主元个数的计算，运用于pca以及pls的数据分析算法中(the calculation of principal components)

cpio源码,cpio2-11,不要钱了，随便看看(cpio code)

说明：  A星算法，机器人的路径规划，自己选择起始点和终点。运行astar.m文件就可以了(A star algorithm Robot path planning Suitable for novices to choose the starting point and ending point)

说明：  一本很適合新手入門的MATLAB工程書，希望大家可以學到東西(A Guide to MATLAB for Beginners)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.

本案例通过对图像加入高斯噪声，利用sym4小波函数对该图像和信号进行三级分解，用小波阀值去噪的方法对该图像进行去噪，并给出了仿真结果。(This case through join Gaussian noise image, use the sym4 wavelet decomposition of the image and signal, the wavelet threshold to filter method for the image denoising is presented, and the simulation results.)

The M-file computes the spectral correlation function or cyclic spectral density using the FFT accummulation method.
