求助matlab小波分析(有数据)
菜鸟求助matlab小波分析(有数据)本人刚刚接触matlab,想对一组数据进行小波分析(用墨西哥帽小波,mexh函数),但是不知道如何实现,请各位前辈赐教,感激不尽!数据如下:ty01.7126340.3321.6142060.6341.7520050.9621.7520051.2541.2401831.5890.866161.8170.8858452.0030.905532.2860.9547442.5311.0039582.8280.8858453.1240.7677323.5830.6594623.7140.5511923.9950.5034594.1160.5511924.4350.5216644.6910.4921364.8380.7382045.0760.9842725.3294.7540355.6348.5237975.9689.7541386.37610.984486.62211.594736.86812.204987.00311.949067.20111.693157.42612.273877.61412.85467.84112.30348.02411.752218.26912.116398.58512.480578.93213.395949.14614.311329.33813.888089.51513.464849.72314.163681014.86251
这些数据是类似于(a)图的数据,只要最后能画出类似于(b)图就行:

不知对不对?希望有高人能够指点t=;
y=;
plot(t,y);
coefs=cwt(y,,'mexh','plot') t=;
y=;
plot(t,y);
coefs=cwt(y,,'mexh','plot') 二楼的,你的程序不对啊,我COPY去运行,没有得到期望的结果!! 本帖最后由 wdhd 于 2016-9-14 10:20 编辑
