Using wavemngr function on Matlab R2015a on mac os x?

I wanted to add a new wavelet using wavemngr on Matlab R_2015a. I am following MATLAB instructions on the help page named "pattern adapted wavelets for signal detection". But, when using "wavemngr" i get the following error message:

Undefined function 'wavemngr' for input arguments of type 'char'. As I used exactly the same argument than in the example given on the help page I mentioned before, I opened the wavemngr function and the execution stops at the command "wavemngr('clear')" I also tried to see every wavelets there are on the toolbox using "wavemngr('read')" and i get the same error message.

I am working on a MacOSX 10.10.3, and I thought this could be a problem of compatibility between wavemngr function and the java version on MacOSX, has someone already encountered this problem ?
