说明：  基于matlab 的信号处理方面的程序实现，包括幅频特性，滤波器的设计等(These are program examples about signal and system based on matlab )

实现并比较不同梯度边缘检测方法(普通梯度、Robert、Sobel、Prewitt、Laplace、LOG和Canny) (Implementation and compare the different gradient edge detection method (general gradient, Robert, Sobel, Prewitt, Laplace, LOG, and Canny))

This code is used to simulation of bed load transport in two phase flow domain.

mfcc用于求取训练样本的特征值，其需要melbankm和enframe两个程序。 enframe用于将语音分帧，melbankm用于产生mel三角滤波器组，vqlbg用于获取说话人码书，disteu程序用于计算两个矩阵间的距离，(mfcc strike eigenvalues ​ ​ for the training sample, which requires melbankm and enframe two procedures. enframe for the voice of the frame, melbankm used to produce the triangular mel filter bank, vqlbg codebook is used to get people talking, disteu procedures used to calculate the distance between two matrices,)

时频分析工具箱，找了好久的，用起来不错的(Time-frequency analysis toolbox, looking for a long time, and using up a good)

genetic algorithm based on matlab，The Genetic Algorithm (GA) is a good method to solve optimization problems. Genetic algorithms are search and optimization methods based on natural evolution. They consist of a population of bit strings transformed by three genetic operators: selection, crossover and mutation

code for finding maximal solution of max-product fuzzy relation equation

研究生时的现代信号处理的作业，在MATLAB中求图像纹理特征，基于分段非线性权重值的Pso算法，最大信噪比的独立分量分析算法，快速扩展随机生成树算法。( Modern signal processing jobs when the graduate, In the MATLAB image texture feature, Based on piecewise nonlinear weight value Pso algorithm, SNR largest independent component analysis algorithm, Rapid expansion of random spanning tree algorithm.)

可以对任意实现频谱细化，函数的参数见函数自身说明(Spectrum can be achieved for any refinement, the function of the parameters see the description of the function itself)
