图片（bmp,jpg等）与DAT格式文件相互转换，实现DSP读取，存取图像，另附《Matlab辅助DSP进行图像处理应用开发》(Photo (bmp, jpg, etc.) and DAT format files converted with each other to achieve DSP read, access images, attached " Matlab-assisted DSP for image processing application development" )

Sunspot activity is cyclical, reaching a maximum about every 11 years. Let s confirm that. Here is a plot of a quantity called the Zurich sunspot relative number, which measures both number and size of sunspots. Astronomers have tabulated this number for almost 300 years.

有一个信号，如果抽样频率，设计一个M点滑动平均系统，要求虑除信号中500Hz的成分，用MATLAB编程仿真结果，确定M的值并画出滑动平均系统的幅频特性图。(Have a signal, if the sampling frequency, to design a M point moving average systems, requirements, in addition to the composition of 500 hz in signal with MATLAB simulation results, determine the value of M and draw the amplitude-frequency characteristics of moving average systems. )

可以求取一维信号的模糊熵,比如心电信号就可以用这个程序来做模糊熵；另外一个是得出混淆矩阵(The fuzzy entropy of one dimensional signal can be obtained.For example, ECG signal can be used to do fuzzy entropy with this program.The other is to get the obfuscation matrix)

图像去噪声，图像中有噪声，可去除噪！！！！！！！！！！(image remove noise )

经验模态分解(Empirical Mode Decomposition, 简称EMD))方法的MATLAB代码(EMD (Empirical Mode Decomposition, referred to as EMD)) ways of MATLAB code)

本文当中包含了matlab的主要命令，如管理命令和函数(This article contains the main matlab command, such as management commands and function)

各种算法的matlab代码，方便你们学习和使用，全为matlab编写(Genetic algorithms, particle swarm optimization algorithm examples of easy to learn and use you, all written for the matlab)

用MATlab实现的粒子群算法，比较简单，适用于刚学习粒子群算法的人，大家可以交流一下(MATlab particle swarm algorithm, relatively simple, suitable for people new to the study of the particle swarm optimization (pso) algorithm, we can discuss)

BFT,正交傅里叶变换，用于检测线性调频斜率的方法。仿真与论文结果一致。(BFT, orthogonal Fourier transform for detecting the slope of the linear frequency modulation method. Simulation results are consistent with the thesis.)
