Matlab编写的路标识别程序，可以对一幅图像中的多个路标进行识别。对雾化图片效果很好！(Matlab program written in road signs recognition, an image can be identified in a number of signs. Good effect on the atomization pictures!)

这是一个用系统模型辨识用的PSO程序,它主要是用于系统的参数未知时,此时比较方便.(This is a used system model identification procedures used in PSO, it is mainly used for systems with unknown parameters, the more convenient at this time.)

单边指数信号M文件，可生成单边指数信号频谱，希望对大家有帮助(Pors)

matlab实现的关于数字信号处理2的一个AR模型的程序，大家可以看一下了啊。。。。。(matlab implementation of digital signal processing on an AR model of 2 procedures, we can look at the ah. . . . .)

对录音信号集 中的某一语音，利用BATLAB设计一美尔例谱算法，并实现。 取信号集 中的一个语音信号：“xxxxxx”，将它作为输入的语音信号来为设计一个美尔倒谱算法，在该算法中，主要设计了以下环节： 1.读入一个语音信号；2.对这个信号归一化；3.对归一化的信号进行加窗处理（这里的矩形窗长度必须为257，重帧长64）；4.进行预加重处理，即通过一个高通滤波器： ；5进行512点的FFT；6.分别取模平方得到功率谱；7.在设计的mel滤波器组中，我采用了25个带通滤波器；8.将得到的功率谱信号通过mel滤波器组，得到相应的25个功率值；9.对这些功率值取自然对数；10.对这些值取离散作弦变换；11.将得到的值去掉直流分量，取其它值作为MFCC参数。 (Concentrated on recording a voice signal, using BATLAB designed Mayer cases spectral algorithm, and implementation. Get a voice signal signal focus: "xxxxxx", will it as input for the design of a voice signal to Mel Cepstrum algorithm in the algorithm, the main design of the following links: 1. Read a speech signal 2. On the signal normalized 3. Of the normalized windowed signal processing (here, rectangular window length must be 257, re-frame size 64) 4. For Pre-emphasis processing through a high-pass filter: 5 for 512 points of FFT 6. modulo square were obtained spectrum 7. in the design of mel filter banks, I use a 25 band-pass filter 8 . will be the power spectrum signal by mel filter bank, corresponding to the 25 power values 9. on the power to take the natural logarithm value 10. to take these values as strings of discrete transform 11. will be of value to out DC component, to take other values as MFCC parameters.)

Petri网: 基本概念和分析方法 ，对学习perti网仿真和很有帮助(Petri nets: basic concepts and analytical methods, simulation and helpful to learn perti Network)

使用ｍａｔｌａｂ计算交易价的ＶＷＡＰ。是程序化交易和算法交易的必备代码。(Matlab calculate the trading price of the VWAP. Program trading and algorithmic trading must code.)

对仿真信号进行快速傅里叶变换，再进行经验模态分解，再对每个分量求FFT(Simulation signal fast Fourier transform, and then empirical mode decomposition, and then seek FFT for each component)
