巴特沃斯滤波器，对已遭破坏的影像进行还原，能够有效的改善影像品质。(Butterworth filter, to restore the image has been damaged, can effectively improve the image quality.)

A good matlab code that analysis the ROC curve and corresponding AUC value to estimate the sensitive and the currectness of the sample estimate. This code is suitable for variable type and function data.

PCA 源代码 使用MATLAB PCA 源代码 使用MATLAB(PCA source code using MATLAB PCA using MATLAB source code)

[Numerical analysis]_ This algorithm computes the root of a function by the Wijngaarden_Dekker_Brent method.

利用matlab/simulink搭建了水轮机调速系统模型，考虑了频率死区和速率限制(model the hydraulic turbine governing system by matlab/simulink, considering the dead band and ramp limit )

Voice quality assessment

学习bp神经网络的一个例子，有助于理解bp(bp nn MATLAB)

learning with hyper graphs

支持向量机，用于分类，含训练集与测试集，用SVM进行多分类(Support Vector Machine (SVM), used for classification, including training set and test set, and multi-support vector machine (SVM))

信道化软件无线电技术不仅能同时发射整个处理带宽内所有信道上的信号，而且具有很高的计算效率，实时处理能力强，结构简单，可实现性强。这种信道化发射机与信道化接收机一样也是基于多相滤波器来实现的。(Channelized software radio technology can not only transmit signals on all channels in the whole processing bandwidth at the same time, but also has high computational efficiency, strong real-time processing ability, simple structure and strong realizability. The channelized transmitter is also implemented based on polyphase filter as channelized receiver.)
