很好的一本matlab参考书，上传个大家，供大家参考，下载使用(digital signal process matlab)

matlab时频分析工具箱时频分析工具箱time-frequency analysis toolbox 第二代，比第一代增加了许多信号处理的函数，有些函数进行了功能的增进。使用的时候，解压到MATLAB安装目录的toolbox目录下，并在matlab中将其添加到搜索路径中使用。(time-frequency analysis toolbox matlab second generation than the first generation adds many signal processing functions, some functions have been enhancing features. Use it, extract it to MATLAB installation directory toolbox directory and search paths to work.)

粒子群算法，思路清晰，有详细的解释，便于理解(Particle swarm optimization, clear thinking, there is a detailed explanation, easy to understand)

说明：  基于matlab。利用FFT计算信号的频谱并与信号的真实频谱的抽样比较。 脚本文件T2F.m定义了函数T2F，计算信号的傅立叶变换。(Based on matlab. Calculated using FFT frequency spectrum and the true spectrum of the signal sample comparison. Script file defines a function T2F.m T2F, calculate the Fourier transform of the signal.)

三电平逆变，其畸变系统THD比两电平稍好(PWM Generator (3-Level) Block Example)

用于计算莫尔圆，只要输入相关数据，就可以轻松得到所要求的数据，采用MATLAB编写。(Used to calculate the Mohr circle, as long as the input data, you can easily get the required data, using MATLAB preparation.)

说明：  三歩搜索法，是运动估计中块匹配方法的一种简便搜索方式 (Three-step search method, block matching motion estimation is a convenient way to search method)

OFDM的MATHLAB仿真，计算误码率，误比特率，π/4qpsk调制(OFDM-MATHLAB simulation, the calculation error rate, bit error rate, π/4qpsk modulation)

基于MATLAB的谐波电流检测方法的建模与仿真(MATLAB-based harmonic current detection method of modeling and simulation)

说明：  改程序用于在实验中所测量的振动、噪声、水声以及数值模拟监测所得到的信号，实现信号的短时傅里叶变换分析。(The program is used to measure the vibration, noise, underwater sound and the signal obtained by numerical simulation monitoring in the experiment to realize the short-time Fourier transform analysis of the signal.)
