小波工程主要包括一两部分:一、连续小波分析的应用,二、离散小波分析的应用。下面分两个部分分别说明这两个程序的分析结果:
一、连续小波分析:
所用信号为自己构造的三角波和正弦波叠加的信号:s=(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3+1*cos(n/2)*10。其中第一项(-1).^(floor(n/50)+1).*(mod(n,50)-25)*2为一周期为100的锯齿波,第二项-(-1).^(floor(n/17)+1).*(mod(n,17)-8.5)*3为一周期为34的锯波,第三项为一周期为4*pi正(余)弦波。另外叠加了一幅度为5的噪音信号。
程序包包含程序与说明文档。(Wavelet works mainly consists of two parts: first, the application of continuous wavelet analysis, II, Discrete Wavelet Analysis.)
