遗传算法求解非线性规划问题的两个MATLAB源程序(Genetic Algorithm for nonlinear programming problems two MATLAB source)

训练错误率和交叉验证错误率相等，在样本比较大时，这个结果是可以预期的；训练错误率一般低于测试错误率，但是当样本数据比较少时，实验也出现了意外，样本多的那组测试错误率比样本少的训练错误率还要小；在本实验中，同组数据的交叉验证错误率比独立测试错误率高，这个反常现象是因为样本的原因所致，交叉验证的样本小，而独立测试时所用训练样本数目大，因而出现这种情况。分类线上，fisher准则是一条直线，而贝叶斯分类器实际上是一个类似椭圆的封闭曲线；很明显，贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)

基于matlab的曲线拟合，一种函数的拟合，完整代码(Based on the MATLAB curve fitting based on MATLAB curve fitting)

DOA估计的一种两种常用方法，ESPRIT和TLSESPRIT，程序简洁明了，方便理解(A two common methods DOA estimation, ESPRIT and TLSESPRIT, procedures concise, easy to understand)

说明：  经典的fastica算法，实现盲源分离，速度较快且效果较好(The classic FastICA algorithm can achieve blind source separation with fast speed and good effect)

角点检测程序源码，使用的是HARRIS角点提取方法，效果很好。(Corner detection program source code, using extraction methods HARRIS corner, very good.)

这个程序的主要功能是用来提取特征。其中有分帧算法，并提取MFCC参数作为特征。(The program' s main function is to extract features. Partakers of which the frame algorithm, and extract the MFCC as feature parameters.)

寻找数组中的局部极大值和局部极小值以及其位置的函数( 比较前后5个数据)

余割函数方向图的天线设计，其中给出了设计原理和实物图。(Cosecant pattern of the antenna design, which gives the design principle and the physical map.)
