G7Problem optimizition benchmark problem (test problem) in matlab

说明：  matlab有优化处理问题，是模式识别等机器学习的关键(There matlab optimization problems is the key to pattern recognition and other machine learning)

该程序是QR解矩阵特征值的，matlab程序(The program is the solution matrix eigenvalue QR)

本程序是MATLAB用编写程序计算光子晶体光纤色散问题 准确，逼真(simulate pcf dispersion )

短时傅立叶变换应用示例，展示了如何实现三个点频信号在时域上的分离。(Short time fourier transform application example, showing how to set apart three different signals with different frequencies in time domain.)

Sliding mode control implementation

This file is to optimize functions

说明：  一个关于数值分析的matlab演示，十分有用(A presentation on the numerical analysis matlab, very useful)

Input: x: input image ru, rd: amount of extension, up and down, for rows cl, cr: amount of extension, left and rigth, for column extmod: extension mode. The valid modes are:主要用于图象处理和模式识别( Input: x: input image ru, rd: amount of extension, up and down, for rows cl, cr: amount of extension, left and rigth, for column extmod: extension mode. The valid modes are:)
