OFDM原理matlab图形界面演示程序，本人原创。 OFDMDEMO Demonstrates OFDM Communication System Function: to demonstrate the primary principle of OFDM system To start the demo type "OFDMDEMO" in Matlab. For more information press "help" button ofdmsimple.m is the key code of ofdm simulation(OFDM Communication System Demonstration Program.)

信号谱分析之AR算法，计算信号频谱，用于随机信号分析(The AR_algorithm of analysis of signal，calculating the frequency spectrum ，is used for random signals！)

一个非常经典的核统计学习工具箱。集成了kpca、kdr、ksri等。具有分类和回归双重功能。(A very classic nuclear statistical learning toolbox. Integrated kpca, kdr, ksri and so on. Classification and regression with a dual function.)

实现彩色图像增强，效果不错，是使用matlab编程的(Color image enhancement, the effect is to use the matlab programming)

使用支持向量机进行非线性回归，得到非线性函数y=f(x1,x2,…,xn)的支持向量解析式，求解二次规划时调用了优化工具箱的quadprog函数。本函数在程序入口处对数据进行了[-1,1]的归一化处理，所以计算得到的回归解析式的系数是针对归一化数据的，仿真测(Using support vector machines non-linear regression)

模拟通过一个高度非线性光子晶体光纤(PCF)传播的kW峰值功率孤子脉冲。(These scripts simulate femto-second soliton pulses, with kWs of peak power, propagating through a highly non-linear Photonic Crystal Fiber (PCF).)

选择性消除谐波，通过调试运行，结果精确，且易于自行修改所需参数。(Selective harmonic elimination, through commissioning, operation, results are accurate, and easy to modify the required parameters.)
