This m_file uses a PLL to demodulate an FM modulated carrier

说明：  melbankm函数的源程序。这个函数也要被melcepst函数调用，用来进行计算Mel倒谱系数。这个函数的作用是构造mel滤波器组(function [x,mn,mx]=melbankm(p,n,fs,fl,fh,w) MELBANKM determine matrix for a mel-spaced filterbank [X,MN,MX]=(P,N,FS,FL,FH,W) )

This is the rational fractional polynomial technique for extracting modal properties of a structure

针对“BreastCancer”数据集，作为对比，第一次对特征集直接进行SVM分类，第二次使用粒子群算法进行特征选择后再进行SVM分类。并且对比和分析了两次分类的结果。(For "BreastCancer" data set, as a comparison, the first time the feature set is directly classified by SVM, and the second time the feature set is selected by particle swarm optimization before SVM classification. The results of the two classifications are compared and analyzed.)

Dielectric waveguides. Outstanding handbook in electrooptics. Examples of different methods for analysis of modes of dielectric waveguides .Matlab codes are included.

说明：  matlab声学特性处理；绘制元音立体图；计算LPC谱；提取共振峰。(matlab acoustic characteristics of treatment draw vowel perspective view calculated LPC spectrum extract formant.)

对经典协议LEACH的改进版本，可以出图3个，对初学很有帮助，大家有兴趣的可以看看。(LEACH agreement on an improved version of the classic, you can plot three, very helpful for beginners, we are interested can look at.)

采用matlab实现了GPS单点定位，包括读Ｎ文件、O文件，定位解算，坐标转换等。(Matlab achieved using GPS single point positioning, including the reading of N documents, O file, locate solver, coordinate conversion.)
