文档给出MATLAB源程序，关于遗传算法解决TSP问题。(Genetic algorithm to solve TSP)

这个程序是计算信号的希尔伯特变换的，求信号瞬时相位，瞬时频率(This program is to calculate the signal of Hilbert transform, the signal instantaneous phase, instantaneous frequency)

说明：  给出了天线阵的频率波束响应图及对应程序 是一个完整的实验报告 是我们上课的时候大作业 很全面哦 又需要的下载吧(The frequency beam response diagram of the antenna array and the corresponding program are given. It is a complete experimental report. It is a comprehensive homework when we are in class, and we need to download it)

用灰度共生矩阵提取五个纹理特征 包括：熵、均匀度、相关性、能量、对比度(Extraction of five GLCM texture characteristics，Include: entropy, uniformity, correlation, energy, contrast)

特徵粹取（feature extraction）是特徵選取（feature selection）的延伸，簡單地說，我們希望將資料群由高維度的空間中投影到低維度的空間，因此，我們必須找出一組基底向量（base）來進行線性座標轉換，使得轉換後的座標，能夠符合某一些特性。 我們可以將特徵粹取分成「包含類別資訊」和「不包含類別資訊」兩大類。包含類別資訊指的是我們已經知道哪些資料分別歸屬於哪一類；而不包含類別資訊的特徵粹取則適用於我們不知道手上的資料點分別該歸屬於哪一類，甚至連該劃分成幾類都不知道的情況。對於這兩大類資料，可以分述如下： 對於「不包含類別資訊」的資料，我們通常使用「主要分量分析」（principal component analysis），簡稱 PCA。 (Cuiqu features (feature extraction) is feature selection (feature selection) extension, simply put, we want to base the projection data the high-dimensional space to low-dimensional space, so we have to find a set of basis vectors ( base) to the linear coordinate conversion, so that after the coordinate conversion, can meet a number of features. We can feature Cuiqu into " category contains information" and " does not contain a category of information," two categories. Contains categories of information refers to what we already know what kind of information are attributed to Cuiqu features include categories of information are not applicable to information we do not know the points are in the hands of the home in which category, and even that is divided into several class do not know the situation. For these two categories of information, can be divided as follows: For information " does not include the categories of information" , we usually use the " )
