说明：  语音信号分析软件，提取美尔倒谱系数等等功能(Speech signal analysis software, extract Simmel cepstral coefficient features, etc.)

本资料为细致介绍matlab的安装和应用资料，对于新入门者有很大的促进作用(The information detailed introduction matlab installation and application information, have a significant role in promoting new beginners)

加速度传感器测得的过载信号，通过matlab处理，得到光滑曲线。 其中有滤波，频谱等计算。(The overload signal measured by the acceleration sensor is processed by MATLAB, and the smooth curve is obtained. There are filters, spectrum and other calculations.)

一些好用的matlab小程序，课用于计算一些最小树图，最短路程等(Matlab small number of useful procedures, classes used to calculate some of the most small tree map, the shortest distance, etc.)

两个发射天线，两个接收天线的程序，包括编码，调制，解调等。(two transmit antennas two receive antennas system)

matlab地图工具箱的详细介绍，对需要绘制地图可以一看。(Map of the toolbox matlab detailed description of the need to draw the maps can have a look.)

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.)
