matlab使用工具箱,有利大家对于遗传算法的研究(matlab toolbox to use, enabling everyone for genetic algorithm research)

应用nlms自适应滤波算法进行回声消除的matlab程序，很简单。(application nlms adaptive filtering algorithms eliminate echoes of Matlab procedures, is very simple.)

说明：  （1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 ((1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.)

说明：  产生30行16列的矩阵，每一行代表一路信号，产生32路信号，对32路信号解复用(Produce a matrix of 30 rows 16 columns, each row represents one signal, resulting in 32 signals, the signal demultiplexing 32)

本程序用自然梯度算法实现源信号的分离，给出了平均串音误差(This program uses natural gradient algorithm to achieve the separation of source signals, and gives the average crosstalk error)

说明：  自从发表《RS纠错编码原理及其实现方法》以来，收到很多初识RS编码的读者的来信， 大家纷纷表示这篇文章对初学者很有帮助，但同时也指出了很多不足。比如第一版的例子中都是按照码长 ， 但在实际应用中并不总是这种情况，还有就是MATLAB程序，由于作者在工程中是在DSP上用C实现的， 所以文章中的MATLAB程序只是用来说明问题，并没有经过调试。做事应该有始有终，这次修改， 附有详细的经过调试的MATLAB程序。并尽量做到程序具有通用性。(Since the publication of RS error-correcting coding theory and method, since the RS coding acquaintance received a lot of letters from readers, we have expressed this article helpful to beginners, but it also points out the many deficiencies. For example, the case of the first edition are in accordance with the code length, but in practical applications is not always such a situation, there is a MATLAB program, because the author works in the DSP using C to achieve, so the article in MATLAB program is used to describe the problem and not debug. Things should stay the course, this changes with the detailed procedures after debugging MATLAB. And as far as possible the procedures are inter-operable.)
