这是一个音频特征提取的matlab源代码(This is an audio feature extraction matlab source code)

这里有高斯同态滤波，住址滤波，空域高通滤波，下早后均可直接运行(Here are Gaussian homomorphic filtering, address filtering, spatial high-pass filtering, can be run directly under the early post-)

一个PDF文件，基于小波包的图像压缩处理，并附几个相关小程序(Image compression based on wavelet packet processing, along with several related applets)

A matlab program that illustrates the occurance of aliasing in a digital signal. if the sampling frequency is not sufficient then aliasing occurs.
