I am trying to do a complex 1-D CWT but the wave name cmor1-1.5 is not being accepted and the error message says invalid wavename. However, that is one of the possible choices. I don't understand. If anyone has seen and overcome this problem can you please help ? Thanks

Hi Kim, could you post the part of your code that generates the error? thanks.

Yes, thanks it is scales=(30:2:128); wname = 'cmor1-1.5'; figure c = cwt(m1,scales,'wname','plot');
I just tried actually typing in cmor1-1.5 instead of using wname and it worked, but it would be handy to not have to go through all the code to change the wname THanks

Should just be
c = cwt(m1,scales,wname,'plot');
without the quote.

Hi Kim, How are you attempting to do this:
x = randn(1024,1);
wtcoeffs = cwt(x,1:32,'cmor1-1.5');
Should work, are you trying to use cwtft with that analyzing wavelet?

Yes, but it will only accept it if I actually type in cmor1-1.5 instead of using the previously set wname Thanks

Hi Kim, please see my comment on the top. Your wname already contains the name, no need to add quote. Otherwise, cwt thinks 'wname' is the name of the wavelet.
