Hello,

I have tried both wavelet toolbox 1.0 and wavelet toolbox 2.2. While using the later version for the same simple signal given as an example under help cwt, it gives me a strange error which goes like

??? Error using ==> nargoutchk
Scalar integer value required, but value is an array

Error in ==> errargn at 39
msg = nargoutchk(min(argout),max(argout),argout);

Error in ==> cwt at 56
if errargn(mfilename,nargin,[3:5],nargout,[0 1]), error('*'), end

Wavelet toolbox 1.0 works but I need the newer version to work as it has complex Morlet wavelet option. Did anyone come across this error before? Any help would be really appreciated. Thanks.

Hi Gunjan, These are very old versions of Matlab you are using. I'm not sure it's going to be easy to find someone using those versions of the Wavelet Toolbox. Can you at least post your call to cwt() that is producing the error?

Yes, I use an old version of Matlab (2006a), but my Wavelet Toolbox is
version 3.0.4, so his Matlab must be ancient.

Thanks guys for helping me out here. The call that I am doing is from example which is

t = linspace(-1,1,512);
s = 1-abs(t);
c = cwt(s,1:32,'cgau4');

I have also tried with other simple signals but got the same error back. I am using student version of Matlab 7.0.0.27 (R14). Do you think the student version is a problem? Because my matlab is not that old.

-Gunjan.

Hi Gunjan, You should try not to top post. Threads are easier to follow if you post at the bottom.

I can't see why that example should not run, but I don't have the ability to check against such an old version of the Wavelet Toolbox. The only thing I can think of is that maybe you have another program cwt.m that precedes Matlab's cwt in your path. Although, you appear to be seeing the command line help for cwt (are you looking at the command line help, or the documentation?). If you see the command line help for Mathworks' cwt function when you enter

>>help cwt

then that is not the issue. If you are looking at the documentation, then enter

>>which cwt

to see that you get something like:

toolbox\wavelet\wavelet\cwt.m
