code-QAM

this code implements a svm face recognition

说明：  用MATLAB编写的crc检验查表法程序(Prepared using MATLAB CRC test procedure look-up table method)

量子阱红外探测器用双周期衍射光栅，光栅图形，光强分布等用matlab程序(Quantum well infrared detectors using double period of the diffraction grating, grating pattern, the light intensity distribution program with matlab)

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 )

说明：  duffing分岔图，计算连续duffing方程Lyapunov指数的程序,比较好用(duffing bifurcation diagram, duffing equation for calculating the Lyapunov index procedure, comparative ease of use)

对机械振动信号的预处理，以及滤波，频域变换等(The pretreatment of the mechanical vibration signal, and filtering, frequency domain transform, etc.)
