数值积分方法练习与函数调用：利用ode23或ode45求解线性时不变系统微分方程 =Ay(t)并绘出y（t）的曲线，式中 =0， =4 (Using ode45 ode23 or to solve the linear differential equation when the same system = Ay (t) and draw y (t) curve, type = 0, = 4 )

说明：  此程序用于去除信号中的噪声，并且它是基于小波变换的代码，很实用的(This program is used to remove signal noise, and it is based on the wavelet transform code, very useful)

说明：  The anisotropic diffusion filter is formulated as a process that enhances object boundaries by performing intra-region as opposed to inter-region smoothing

matlab环境下计算MFCC参数（mel倒谱参数），lpcc参数（线性预测倒谱）和pitch（基因）(calculate mfcc lpcc pitch )

该程序模拟了降落伞的下降过程，其结果对于类似问题有借鉴作用。(The program simulates a parachute drop in the process, the results serve as a reference for similar problems.)

说明：  一个ofdm的matlab仿真程序，直接运行即可(the Matlab simulation procedures can be run directly)

Face Recognition Based on Polar Frequency Features

目前matlab国赛比较流行的算法（图论问题）第一步：最短路第n步还会陆续上传。欢迎使用(At present, matlab country match algorithm is more popular (graph theory) the first step: the shortest path step n will continue to upload. Welcome to use)

circular convolution code in matlab

离散卷积图法的MATLAB实现程序，MATLAB函数conv只能计算从零开始的两个右边序列的卷积，此程序对序列没有此限制，适用范围更广。(MATLAB discrete convolution diagram method to achieve the program MATLAB function conv can only calculate the convolution of the right sequence from scratch, this program sequence does not have this restriction applies to a wider range.)
