用c++实现的第二代小波（提升小波）变换，该程序简单易懂，很实用，强力推荐。-Using c++ implementation of second generation wavelets (lifting wavelet) transform, the program easy to understand, very practical and highly recommended.

在理解了离散小波变换的基本原理和算法的基础上，通过设计VC程序对简单的一维信号进行小波分解系数；再通过改变分解得到的各层高频系数进行信号的小波重构达到消噪的目的-Understand the discrete wavelet transform in the fundamental principles and algorithms, based on the VC program by designing a simple one-dimensional signal wavelet coef

非常适用、简单的快速傅里叶变换程序。用c编的。-Very applicable, simple FFT program.
