matlab对语音信号滤波，并比较滤波前后的音效。(matlab on the voice signal filtering, and compare the sound before and after filtering.)

说明：  数学实验matlab的好程序，给matlab的初学者(Good mathematical experiment matlab program to matlab for beginners)

布朗运动的模拟:模拟了在一个有界平面内，N个点进行布朗运动后的分布情况(brownian motion)

线性预测编码的实现 对于初学者来说还是比较好用的

说明：  别人文章中的BP-PID的S函数，可以试一试(BP-S function)
