线性非局部均值滤波器

这是一个利用MATLAB利用PCA实现的简单分类程序，对于模式识别的初学者学习PCA知识并进行仿真会有很大帮助，其中male.txt和female.txt是训练样本，test.txt是测试样本，分类效果非常好。(This is a use of MATLAB to use a simple classification of the PCA implementation process, the PCA pattern recognition study for beginners and simulation of knowledge would be of considerable help, and one of male.txt samples female.txt training, test.txt is the measurement, very good classification results.)

相控阵天线波束图，描述了最简单的相控阵波束图的形成(Phased array antenna beam map, describes the most simple map phased array beam forming)

Function to find SNR gain for a Suprathreshold Stochastic resonance detector and hence compute the optimal value of sigma, which is the optimal amount of noise to be added in order to obtain the highest SNR.

simple experiment on pid along with fuzzy comparision

Dynamically create a variable. This should create a context extension.
