自己编写的三维图形显示通用程序，对理解图形构成非常有帮助！以及小波信号的四级分解程序，对学习小波的人有意义。-I have written three-dimensional graphical display common procedures, understanding of graphics constitute a very helpful! And 4 wavelet signal decomposition procedures, a person of learning mean

MATLAB实现声音信号的小波分解与重构内副数据 不错的-MATLAB voice signal wavelet decomposition and reconstruction of the pair of data is good
