电力系统潮流计算中雅可比矩阵形成的程序，使用MATLAB编程(Power System Load Flow Jacobian matrix formation process, using the MATLAB programming)

鲁棒性非常好的ICA算法程序，做独立成分分析时候效果好(robust-ICA)

This code calculate the steady seepage fo a concrete dam. The program is written in a manner that you can easily change the problem information. To understand how the program works, run main.m then follow the mentioned subroutines (.m files). There is enough comments in all .m files.

MUSIC方法估计信号方位(MUSIC methods are used to estimate the signal direction)

高阶频谱分析工具(数字信号处理Matlab例程)(higher order spectral analysis tools (digital signal processing Matlab routines))

该文件可以让您的c从入门到真正的精通（在supn中）(from this file,you can learn a lots about c program in uspn)

说明：  几种传统的图像插值放大方法：最近邻插值法，双线性插值法，双三次插值法(Several traditional interpolation to enlarge the image : nearest neighbor interpolation, bilinear interpolation, bicubic interpolation.)

基础的doa代码，基于基本的music算法，简单易懂，适合初学者对music算法的理解，吐血推荐，希望对大家有所帮助。(basic music on doa.)

优化的模糊熵Code for computing approximate entropy for a time series(Fuzzy Entropy )

理解快速傅里叶变换和反变换的好资料，是在MATLAB环境下联系的例子 (it is a good materials of understand the fast Fourier transform and inverse transform.)
