Normalized cross-correlation function, contains all of the right to cross-correlation function, can easily use it

录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；通过matlab界面进行编程设计，界面方便人们操作( Their record a voice signal, and recording the signal is sampled draw sample after the time-domain waveform and frequency spectrum of the speech signal designed by matlab programming interface, easy for people to interface)

algorithm for speech enhancement

说明：  电力电子12脉冲（NVDC），大多数matlab版本会缺失的库文件(Power electronics 12 pulse (nvdc))

说明：  偏最小二乘法的原始程序，粒子群优化算法对支持向量机SVM的优化。对初学者有帮助。套用模型，可以改PSO-SVR。(Partial least squares method of the original program, particle swarm optimization algorithm for support vector machine SVM optimization. It is helpful for beginners. Applying the model, PSO-SVR can be changed.)

说明：  matlab中文帮助文档，方便读者理解阅读matlab，一般的安装软件中的帮助文档是英文的，使用不方便(matlab Chinese help docment, support read convience and help you understand clearly )

说明：  多变量寻优的源码，包括基本算法如下：DFP法（又称变尺度法），BFS法、一阶梯度法，共扼梯度法。(multivariate optimization of the source code, including basic algorithm is as follows : DFP Act (also known as the variable scale), BFS, a ladder degrees, a total of the accused gradient method.)

说明：  BPSK.QPSK的MATLAB仿真程序 (BPSK.QPSK matlab program)

首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(M script file canshuo.m first enter the node number and the right path lies in the command window enter canshu, with s = 12, e = 10 The format of the input requirements of the start and end points, and then enter the main between two points can be obtained path and length.)

基于matlab 的MP3音频播放器。能够实现播放、暂停、停止等基本功能。同时可以绘制波形图。(Matlab-based MP3 audio player. Enables play, pause, stop, and other basic functions. At the same time you can draw waveforms.)
