afqrrls1算法例程，希望对大家有所帮助(afqrrls1 algorithm routines, and they hope to help everyone)

这个是计算光子晶体禁带程序，对新手有借鉴意义。改写其中的参数(Calculate the photonic crystal band gap)

implements the GOST 28147 OFB counter mode (GCTR).

一种典型的人工蜂群算法（ABC）的MATLAB仿真实例，注释很详细。(A typical artificial bee colony algorithm (ABC) MATLAB simulation examples, very detailed notes.)

基于Matlab平台开发的用于特征选择的算法，后向选择算法，主要用于提取心电生理信号的表示特定情感的特征用于降低特征维度。(Backward selection algorithm for feature selection algorithm based on Matlab platform development, mainly for extraction of ECG physiological signal represents a specific emotional characteristics used to reduce the feature dimension.)

包括最小二乘法、SVM、神经网络、1_k近邻法,小波包分析提取振动信号中的特征频率，利用最小二乘算法实现对三维平面的拟合。( Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Wavelet packet analysis to extract vibration signal characteristic frequency, Least-squares algorithm to fit a three-dimensional plane.)

基于LMS的双向回波削除源码，不过回波幅度不要大于0.2,否则算法认为DOUBLE TALK DETECT。各位可修改此阀值，试试效果(based on the two-way LMS Echo slashing source, but not greater than the rate Echo 0.2, or that the algorithm** DOUBLE TALK. You can modify this threshold, try Effect)

一个修改后的PCA进行人脸识别的Matlab代码~~~~~~~!!!(A revised PCA for Face Recognition Matlab code ~~~~~~~!!!)

说明：  两个方向的二维主成分分析matlab算法(Two directions of two-dimensional principal component analysis algorithm matlab)
