Concerning Bretschneider

[Coucou2016]

After download the package, I tried to run the script example_waveFields_1.m, which seems to me a good start point.
I find that there is an error about the name consistency of the bretschneider class. I changed the name bretschneider to Bretschneider in both the folder and the script and solved this problem.
However, I continue to find a new error about not defining * for the class Bretschneider in the line
SG = S'*G; % create a matrix of the spectral amps
I know that it is due to the fact that matlab can not use * for a newly created class by you, but I still don’t know how to correct it.

I would like to ask you, if possible, to help me address my issues, If you have the time. I would greatly appreciate any help you can provide.

Thank you very much for your time and patience. I look forward to hearing from you.

Hello and sorry for the delay in replying. In place of the original code that called a (now seemingly non-existent) 'bretschneider' function, you should use
S = Bretschneider.MakeSpec(Hs, 1./fm, 1./f); % Bretschneider spectrum
Notice that I am using the method on the Bretschneider class, so that a numeric vector is returned. Notice also that this class is expecting inputs in terms of period, hence the change to 1./ inputs.
