提取图像的SPAM686维特征，可以用SVM来进行隐写分析(Extract images SPAM686 dimensional feature, you can use SVM to steganalysis)

多模板去噪的matlab源代码，对不同模板进行比较(Multi-template denoising matlab source code, a comparison of different templates)

用matlab实现的最大化负熵的独立分量分析方法，作了正交化处理，可以同时分离出所有的独立分量（无噪声条件下）(Using matlab to achieve the maximization of the negentropy method of independent component analysis, orthogonal made of processing, can be isolated from all of the independent component (no noise))

In this presentation the method of least squares will be used to derive a recursive algorithm for automatically adjusting the coefficients of a tapped-delay-line filter, without invoking assumptions on the statistics of the input signals. This procedure, called the recursive least-squares (RLS) algorithm.

一个简单的matlab整流仿真程序，依据数学公式搭建，但出的波形不是很理想(A simple rectifier Matlab simulation program, based on a mathematical formula to build, but the waveform is not very satisfactory)

说明：  六脉冲三相可控整流器的MATLAB/simulink实现方法仿真模型。(Three-phase six-pulse controlled rectifier of the MATLAB/simulink simulation model realization.)

This example solves a 2nd order wave equation: utt = uxx + uyy, with u = 0 on the boundaries. It uses a 2nd order central finite difference in time and a Chebyshev spectral method in space (using FFT). It compares to running the same algorithm on the GPU using gpu-arrays and built-in functions available for the GPU.
