用MATLAB实现数字信号处理的程序，包括FIR、IIR设计，以及Z变换、FFT变换(Using MATLAB realize digital signal processing procedures, including FIR, IIR design, as well as the Z transform, FFT transform)

FT3 M-file for ft3.fig FT3, by itself, creates a new FT3 or raises the existing singleton

matlab多因子选股模型，计算每只股票的得分，根据股票的得分划分为n个区间(matlab multi-factor stock selection model to calculate the score for each stock, based on the stock s score is divided into n intervals)

说明：  这是一个matlab的直方图均衡程序，先读入一副彩色图像，将其转成灰度图，输出该图的直方图，做均衡以后再次输出，可以看到均衡后图像直方图比较均匀了。(this is a histogram program based on matlab)

基音检测的MATLAB程序，好含有分帧程序，短时域所有相关分帧处理算法代码。(Pitch detection MATLAB.)

Fit calculates coefficients c of the least-squares approximating polynomial

matlab 源码,基于小波变换的语音信息隐藏的实现,对原始语音信息和水印信息都经过三层小波分解处理后,将水印信息的低频信号嵌入原始语音信号的部分高频信号部分实现隐藏.源代码不仅给出隐藏过程,并且给出的在随机噪声,重采样,信息压缩情况下的抗攻击特性.源代码清晰有注释(matlab source code, based on wavelet transform voice messages hidden realize, the original voice information and watermark information after a three-treatment, after wavelet decomposition, the watermark information embedded in the low-frequency signals of the original speech signal realize some hidden part of high-frequency signals. source code is given not only to hide the process, and given in random noise, resampling, compression of information in case of anti-attack features. source code has a clear Notes)

微粒群(PSO)优化算法进行图像匹配程序，MATLAB版。(Particle swarm optimization (PSO) algorithm for optimized image matching program, MATLAB version.)

本文的程序实现在屏幕上随机产生不同大小的雪花，并以不同的速度下降。相对于第一版，它在很多性能上做了优化，直接在桌面的上下文中绘制雪花。而且，现在也通过RedrawWindow，实现在桌面的图标(如任务栏)上绘制雪花了。你可以用它来学习GDI。(Falling Snow on Your Desktop! Part II This article explains how to create an application that makes it snow on the desktop. Since my previous article was published, I received many user inquiries about how to improve the program. This article demonstrates how to create snow flakes that fall on your desktop, by using the draw functions directly in the desktop context. When the application starts, it creates an array of snow flakes and starts the timers for each flake. Manipulation of the RedrawWindow function allows the drawing of flakes behind and over the desktop icons, making the application more impressive. )

this is for demo in matlab
