TWISTER Uniformly distributed pseudo-random numbers

说明：  利用三种方法解决Volterra的两个种群的生态学问题。(Volterra use three methods to solve the problem of two populations of Ecology.)

THE REGULATOR OF SPEED OF DOUBLE FEED INDUCTION GENERATOR

基于Davenport谱与谐波叠加法，生成脉动风速。(Based on Davenport spectrum and harmonic superposition method, generate pulsating wind speed.)

Non-decimated wavelet transform, redundant wavelet transform, stationary ％ wavelet transform(Non-decimated wavelet transform, redundant wavelet transform, stationary wavelet transform)

Toolbox to implement SOM nural network in matlab

matlab code for pitch of speech signal

利用matlab和ug联合进行齿轮设计，先求解，再建模，思路很新鲜(Ug joint use matlab and gear design, first solved, and then modeling, very fresh ideas)

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.)

语音信号处理矢量量化的LBG算法，又称K-mean 算法(in speech signal process vector quantization technology using LBG algorithm with matlab language)
