文件包含三个子文件:dec.m,test_dec.m,recon.m
dec.m文件使用MATLAB语言自己动手编写小波分解算法;
test_dec.m使用MATLAB语言测试dec.m文件中自己编写的小波Mallat分解算法正确性
recon.m使用MATLAB语言自己动手编写Mallat重构算法
函数使用MATLAB语言,没有调用MATLAB小波分解函数,而是自己动手编写的小波Mallat算法对含噪声的信号进行分解、重构;这对对小波分解的初学者,加深对小波分解有着引导作用。(The file contains three sub file: dec.m, test_dec.m, recon.m
The dec.m file using the MATLAB language to write my own wavelet decomposition algorithm
Wavelet Mallat test_dec.m using MATLAB language test in the dec.m file to write your own decomposition algorithm correctness
Recon.m uses the MATLAB language to write my own Mallat reconstruction algorithm
Function of the use of MATLAB language, do not call the MATLAB wavelet function, wavelet Mallat algorithm but prepare yourself for decomposition and reconstruction of signals containing noise this pair of wavelet decomposition for beginners, deepen their understanding of the wavelet decomposition has a guide role.)
