使用MATLAB制作gui，有代码举例，有ppt说明(Produced using MATLAB gui, there is the code example, there ppt shows)

稀疏分解在LFM信号模型的应用，稀疏分解应用在低信噪比的情况下，能够很好的恢复原信号(mp—LFM)

说明：  自己整理的关于shape context。有matlab代码和word文档，word文档是关于shape context原理的介绍。相当全面。(Their order on the shape context. A matlab code and word document, word document is an introduction on the principles of shape context. Quite comprehensive.)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

matlab 中EMD 经验模式分解工具箱 附带安装说明(the empirical mode decomposition EMD matlab toolbox comes with installation instructions)

qpsk over rayleigh channel

说明：  这些程序是MIT学生学习Matlab时的教学程序，能面还有个pdf文档附有每个程序所实现的功能(This is the teaching codes at MIT for learning Matlab. hope it is helpful for you.)

对于模式识别中的k均值（也称c均值）问题，给出了matlab实现。(pattern recognition for the k-means (also called c-means), is the realization of Matlab.)

读取segy数据、文件，写道头卷头等等，内置说明书，简单易用(Read the segy data, file, writes head roll and so on, the built-in instructions, easy to use)

ordeig.m——主程序，调用后两者，计算特征值，按顺序排列，使虚部递减 pois.m ——对于平面Poiseuille流通过切比雪夫你拟谱法离散化生成O-S矩阵 Dmat.m ——求解切比雪夫微分矩阵 (ordeig.m main program, after calling two, computing eigenvalues ​ ​ in sequence, so that the imaginary part of diminishing pois.m- for plane Poiseuille flow through Chebyshev spectral method you intend to generate discrete OS matrix Dmat.m- Solving Chebyshev differentiation matrix)
