应用最小二乘法对二阶系统进行辨识，得到相关参数(Application of least squares, second order system identification, are relevant parameters)

数字信号处理应用仿真程序，感谢北航自动化学院王秋生老师(Digital signal processing applications simulation program, thanks to Northern College of Automation, WANG Qiu-sheng teacher)

说明：  mp3read和mp3write是直接写在wavread更换和wavwrite访问MPEG音频MP3文件。其特点包括： -旨在重复wavread完整语法和wavwrite -还支持上的动态下采样和渠道mpg123的合并-文件优化的很长的MP3 -只需要解码的部分-使用popen函数进行编码，以避免大量临时文件（可用时-看到我popenw墨西哥） -试图消除写保护回路的时间序列文件/通过阅读“热身”样本-包括辅助二进制软件包在Linux，Windows，Mac的PPC的，苹果，英特尔，和Mac英特尔- 64位(These versions of mp3read and mp3write are direct drop-in replacements for wavread and wavwrite to access MPEG audio mp3 files. Features include: - aims to duplicate complete syntax of wavread and wavwrite - also supports on-the-fly downsampling and channel merging of mpg123 - optimized for very long mp3 files- only decodes the needed portion - uses popen for encoding to avoid a large temporary file (when available- see my popenw mex) - attempts to preserve time alignment of files through read/write loop by removing "warm up" samples - package includes helper binaries for Linux, Windows, Mac-PPC, Mac-Intel, and Mac-Intel-64bit )

粒子群优化算法，粒子群优化算法基本流程，稍加修改即可应用(Particle Swarm Optimization)

输入任何三尺度多小波的尺度函数的系数，可画出其图象(Enter any three-scale Multiwavelet coefficient scaling function can draw its image)

本程序主要利用小波分析的mallat算法实现谱分析的功能(The main advantage of wavelet analysis procedure mallat function of spectral analysis algorithms)
