functionsofmatlab

FFT快速傅立叶变换的代码，只需要Matlab环境即可运行。需要输入分析数据。(FFT Fast Fourier Transform code, only need to run Matlab environment. Need to enter data.)

字符识别，具有一定的准确率，参考使用。MATLAB预言编写的代码(Character recognition, with some accuracy, use and reference. MATLAB code written prophecy)

这是对脑电波处理的共空间模式的matlab程序，主要是提取脑电波的空间特征，并进行降维，然后用支持向量机进行分类。(This is the space of brain wave processing of model of the matlab, mainly is the space of the brain wave characteristic extraction, and dimensional reduction, then classified by support vector machines (SVM). )

matlab入门级别的电子书，主要是基本的操作运算和一些matlab的常用函数汇总(matlab entry-level e-books, the basic operation of arithmetic and some of the commonly used matlab function summary)

说明：  前推回代法通用matlab程序,收敛性好！(Before backward substitution method General matlab program, Convergence!)

该文件包含spwm的单极性和双极性MATLAB smulink仿真，可以正确运行，载波与调制波波形清晰完美。由本人原创搭建。(This file contains the SPWM unipolar and bipolar MATLAB smulink simulation which can run correctly, carrier and modulation wave forms are perfect.)

通信中的采样钟恢复，用gardner 算法提取时钟误差。(STR for sampling Time recovery)

非常有用，采用DWT变换实现数字水印的嵌入和提取(Very useful, DWT transform was adopted to realize digital watermark embedding and extraction)

使用PSO算法求解适应度函数fitness的极值。fitness可以自己任意定义。(PSO algorithm using the fitness function fitness of the extreme value. fitness can define their own arbitrary.)

这是一个非常重要的而又简单的程序，是书上常用和数学建模的好帮手(nice work )
