Matlab source code for Euler to Quaternion conversion.

基于matlab/simulink的三相PWM逆变器仿真建模，希望对大家有所帮助(Based on matlab/simulink three-phase PWM inverter simulation modeling, we hope to help)

说明：  用于语音识别的DTW算法，衍生到地震信号对齐。其中还有一些测试程序。(DTW algorithm for speech recognition is derived from seismic signal alignment.)

本文件提供了几个数值分析中的Matlab小程序。水平有限，多多海涵。(This document provides several numerical analysis of Matlab small programs. Limited, and many Haihan.)

resampling program in matlab

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)
