一个好使的用粒子群优化算法进行特征选择和SVM参数优化MATLAB环境源码

学习MATLAB发的好教材，本电子文档主要讲解了MATLAB的主要算法设计，里面有详细的说明(Learning the MATLAB hair is good material , the electronic document explains the MATLAB algorithm design , which are described in detail )

说明：  this is matlab based signal processing code

in this code random noise is denoise by wavelet and find the parameter for best wavelets

对图像进行预处理，然后进行经典的阈值分割，形态学分割以及种子区域生长。(Preprocess the image, and then the classic threshold segmentation, morphological segmentation as well as seed region growing.)

积分计算实例，二维积分-体积，计算二维曲面面积。(Calculated two-dimensional surface area)

主成分分析，是考察多个变量间相关性一种多元统计方法，研究如何通过少数几个主成分来揭示多个变量间的内部结构，即从原始变量中导出少数几个主成分，使它们尽可能多地保留原始变量的信息，且彼此间互不相关.通常数学上的处理就是将原来P个指标作线性组合，作为新的综合指标。

说明：  这是一个超宽带PPM接收机的程序，用于接收超宽带信号，是用MATLAB编程的(This is an ultra-wideband PPM receiver procedures for receiving ultra-wideband signals,and it is programmed MATLAB )

说明：  基于matlab的图像k均值算法，实现对一副彩色图像进行分割。(Matlab image based on k means algorithm, to realize a color image segmentation.)

matlab生成word文档，文件名为测试.doc，并插入了表格和图片(generate word document)
