小波去噪，以Haar和db4小波基为例的去噪代码-wavelet，haar，db4

用下面的程序产生并显示与小波db4相关联的四个滤波器组.小波函数db4的迭代生成过程.单尺度一维离散小波分解与重构-With the following procedures and display associated with the db4 wavelet filter banks of four. Db4 wavelet function to generate the iterative process. Single-scale one-dimensional discrete wa

本文件调用matlab小波分析包，可以实现db4等小波函数类型的分解和重置，并进行原始信号和重构信号的误差比较！-This document calling matlab wavelet analysis package, you can achieve db4 wavelet function, such as the type of decomposition and reset and reconstruct the original signal and the error signal
