灰色预测模型在Matlab的语言编程(基于GM（1，1）模型)自己编的，很简单。就是为了当时处理数据方便。只是预测下一个数据，如果想得到更多的预测数据，可以在添加。(Gray prediction model in the Matlab programming language (based on GM (1,1) model) own, and very simple. At that time, in order to deal with data that is convenient. Only the next prediction data, if the prediction would like to receive more data, you can add.)

说明：  用Matlab实现相关分析,并建立其系统界面；对给定的试验数据进行相关分析(Correlation analysis using Matlab implementation and the establishment of the system interface on a given test data correlation)

Simulation of the Bit level Logistic map n is the number of the simulated points. x is the simulated time series. a is the parameter.

分析chirp信号的改进fft算法，该FrFT算法是从matlab论坛中的算法，尝试后可用(Improved FFT algorithm for analyzing chirp signals)

MATLAB图象处理命令集合，可以留作备用(MATLAB image processing command set can be used as backup)

this modified PSO algorithm can solve for constrained optimization problem

2PSK调制与解调matlab仿真，包括高斯信道awgn，误码率分析(2PSK modulation and demodulation matlab simulation, including the Gaussian channel awgn, bit error rate analysis)

自己写的matlab版本的径向对称定位眼睛虹膜的程序 效果相当不错 吐血推荐给大家了 希望大家用的时候惦记着开发者的一番心血(Matlab write their own version of the radial symmetric positioning of the eye iris procedures recommended by the effect of good blood to all the hope that by the time the developers concerned about a blood)

matlab中支持向量机工具箱的使用以及一些常用函数的介绍！(Matlab support vector machine (SVM) is the use of some of the most common and toolbox of function is introduced. )

Just a few functions used in my other toolboxes, for computing MSE and PSNR and some other less common image quality metrics.
