这是《小波分析理论与MATLABR2007实现》的源代码。主要是基于Matlab的小波工具箱实现小波基选择、小波包分解、Mallat变换以及小波变换在边缘提取、图像去噪、数据压缩等中的应用，特别包含了二代提升小波的相关内容，理论与实际相结合。大家想要了解的二进小波、正交镜像滤波器组[QMF]等概念这里都有体现。-This is 《MATLABR2007 wavelet analysis theory and implementation》 of the source code. Mainly

Wavelet packet analysis to extract vibration signal characteristic frequency, Is a two hidden layer back propagation neural network, Fractal dimension calculation algorithm matlab code blankets.

matlab代码小波去噪与小波包去噪，可将两者用于比较和学习！--Matlab code about wavelet denoising and wavelet packet denoising, the two methods can be used for comparison and learning!
