this is some basic matlab programs.

this is a source code on digital image corelation and other features as well..

说明：  图与网络学习，主要是与MATLAB结合的方法(Figure and learning, the main method of combining with MATLAB)

Algorithm for frequency analysis usign FFT

Matching Pursuit 算法是信号分解的一种具体实现方法。但其本质上则是一种估计 信号模型参数的方法，因而可直接用于信号检测及参量估计。本文以谐波信号特征参量的估计为例，介绍了其具体实现方法。(Matching Pursuit algorithm is a specific method of signal decomposition. But by its very nature is an estimated signal model parameters, and thus can be directly used for signal detection and parameter estimation. In this paper the harmonic signal characteristics of the estimates of the parameters, for example, describes the specific implementation method.)

MATLAB与外部程序接口，直接调用matlab的算法很方便，推荐使用(MATLAB interface with external programs)
