gaus1 CWT implementation?

[ashayk]

Hi Rafat,

I was wondering if there is a gaus1 CWT implementation available in wavelib? I'm assuming gaus2 is DOG with param = 2, but I'm also searching for a gaus1 CWT implementation. Perhaps I am missing something?

Any help much appreciated.

Thanks,

DOG with param=2 is the Mexican Hat Wavelet. I think you may want to try DOG with param =1. More info here http://atoc.colorado.edu/research/wavelets/bams_79_01_0061.pdf Page 65.

Thanks Rafat,

The docs say param must be a positive even integer for DOG and this is consistent with other implementations (Matlab). I suppose I can try with param = 1, but was hoping you had some ideas.

Thanks.

I haven't looked at the code in quite some time but I believe the algorithm should work for positive integers and not just even ones. Can you post a link to the matlab page so I can take a look ?
