说明：  matlab code to open an image

Inverse discrete cosine transform of an image

正弦信号利用小波分析都分辨路分析的方法去除噪声，分别处理其中的高频和低频系数(Sinusoidal signals are resolved using wavelet analysis method for removing noise path analysis, which respectively deal with high frequency and low-frequency coefficients)

利用声卡采集声音，实现声音的滤波处理。很实用，实用matlabGUI写的。最好用matlab2008a以上的版本打开。(this is a sound filter GUI written by MATLAB.)

一个3-4-1型的mamdani模糊控制系统，可适用于很多情况。(A 3-4-1 type mamdani fuzzy control system, applicable to many situations.)
