对声音信号进行butter低通滤波,对录入的信号进行傅里叶变换，同时对比滤波前后，声音信号的不同(Butter sound signal low-pass filtering, of the Fourier transform of input signals, while before and after filtering, different sound signal)

本程序实现小波在矩阵方程求解中的应用并绘出图形(This program implementation of wavelet in the matrix equations and draw the graph of)

matlab中simulink中用C语言编写S函数模板的翻译版本(matlab in simulink using C language translation S function template version)

prgramm that calculates the greatest common factor of two numbers

这个函数也要被melcepst函数调用，用来进行计算Mel倒谱系数。这个函数的作用是构造mel滤波器组。(This function must be called melcepst function is used to calculate Mel cepstral coefficients. The role of this function is to construct mel filter bank.)
