欠定盲源分离的程序，分离效果很好，适合学习。(Underdetermined blind source separation process, separation effect is very good, suitable for learning.)

说明：  这是一个用遗传算法GA处理实际问题的实例(This is a use of genetic algorithms to deal with the actual examples of problems)

说明：  jack fell down with water

说明：   数据挖掘中的决策树C4.5算法的实现,用matlab实现(Data Mining Decision Tree Algorithm of C4.5, using Matlab to achieve)

说明：  Zhaohua Wu编写的实现eemd的程序。共5个。比较权威。(Zhaohua Wu prepared to achieve eemd procedures. A total of 5. Authoritative.)

这是一个由我本人亲自编写的提取图像特定部分的MATLAB程序。通过使用这个函数，你可以轻而易举地将图像的特定位置用白色矩形线框加以圈定、显示。(If you want to circle the specific area of an image, this little program is much more practical and convenient, thus will help you to mark any area of the image with with rectangle.)

Finite element method programming Matlab

可以很方便的用matlab来编写一维二维三维的莫比乌斯带的图案(Can easily use matlab to write a one-dimensional two-dimensional pattern of three-dimensional Mobius)

一种eemd程序，为学习emd的同学做参考，希望大家多交流学习~(an eemd program，as a reference~)

IIR滤波器设计 一、 实验目的 1、 掌握冲激响应法和双线性变换法设计IIR滤波器的原理及具体设计方法，熟悉用双线性设计法设计低通、带通和高通IIR数字滤波器的计算机程序； 2、 熟悉模拟Butterworth滤波器和Chebyshev滤波器的设计，掌握冲激响应法和双线性变换法设计数字IIR滤波器的方法。 (IR filter design, the purpose of the experiment master IIR filter impulse response method and the bilinear transform design principles and specific design method, familiar with the the bilinear design method to design low pass, band-pass and high-pass IIR digital filter is a computer program familiar analog Butterworth filter and Chebyshev filter design, master the impulse response method and the bilinear transform design digital IIR filter method.)
