MATLAB常用函数整理，希望能对MATLAB初学者有所帮助(MATLAB functions used order, hoping to be helpful to MATLAB for beginners)

本文件是一个SPWM逆变器的仿真源文件，可以在MATLAB7.1中直接运行。设计中PWM Generator采用外部调制信号，并在调制信号中注入了三次谐波，很好的抑制了输出谐波，同时提高了直流电源的利用率。(This document is a SPWM inverter simulation source file, you can directly run MATLAB7.1. Design of PWM Generator external modulation signal, and in the modulation signal into the third harmonic, the output of good harmonic suppression, while improving the utilization of the DC power supply.)

隐马尔科夫树模型，这是一个自包含的程序包，包括2维离散小波变换和逆小波变换 例程。在每个子带中每个刻度的所有小波系数都绑在一起，避免了模型的过度拟合。(This is a self-contained package including the 2-D DWT and inverse DWT routines. All wavelet coefficients at each scale within each subband are tied together to avoid overfitting of the model. )

说明：  通信系统仿真,QPSK调制与解调,主要针对差分解调方式,对于matlab初学者以及做通信仿真的人员有很好的参考价值(communications system simulation, QPSK modulation and demodulation, the main differential demodulator, for beginners and Matlab done Communication Simulation of a very good reference value)

说明：  Enhanced Rotating Machine Fault Diagnosis Based on Time-Delayed Feedback Stochastic Resonance 论文的matlab代码，随机共振(Enhanced Rotating Machine Fault Diagnosis Based on Time-Delayed Feedback Stochastic Resonance)
