this code contain function and simple program for voice pattern recognition using MELCEPST

级联电压型逆变器H桥五电平，目前工业应用较多的一种逆变方式(Cascaded voltage inverter H-bridge five level, industrial applications currently more of a way of inverter)

说明：  use for research in the image processing techniques in medical image processing

This module will calculate the electrical angle between two different signals (Normally current + Voltage). once the first siganl as a reference signal and once the second signal as a reference signal.

Panel Code in MATLAB Coded by L. sankar, April 1997

说明：  采用matlab画螺旋线运动轨迹，速度曲线(Matlab Draw spiral motion track, speed curve)

说明：  用分布傅里叶计算非线性薛定谔方程，改自《非线性光纤光学》第五版。(Calculation of the nonlinear Schrodinger equation with the distributed Fourier)

Signal modulation using Pam modulation (simulink)

ac voltage controller

三电平逆变器的simulink仿真模块，可以输出三个变量，经过调试，可以正常运行。(Three-level inverter simulink simulation module can output three variables, after commissioning, it works.)
