Fourier-transform

此为matlab的代码。包括数值o45算法及o23算法(This is the matlab code. Including numerical o45 and o23 algorithm algorithm)

一维波动方程反演MATLAB程序，采用的梯度法，声波方程，测试可用(1D waveform inversion by gradient method based on acoustic wave equation)

用短时平均能量值对干净的语音信号进行检测，可以区分语音和非语音部分(With short time average energy value to test the clean speech signal, can distinguish between voice and non-voice part )

对于经常使用MATLAB的人员,会经常用到某些函数，而一时之间又想不起这个函数或者不知道如何引用的时候，使用本辞典进行查找将非常方便。希望广大读者能从此辞典中得到帮助。(For often using MATLAB personnel, often used in some function, sudden can not remember when this function or do not know how to refer to the dictionary to find very convenient. I hope readers can get help from the dictionary.)
