Which is the effect of one of the parameters in the cwtft2 command (wavelet toolbox)?

I am using the wavelet toolbox, and executing this command:
cwtstruct = cwtft2(image_matrix, 'wavelet', {'mexh',{2,1,1}}, 'scales',1:1:25,'angles',0);
But if I execute the next one (adding 30 after mexh)
cwtstruct = cwtft2(image_matrix, 'wavelet', {'mexh',30,{2,1,1}}, 'scales',1:1:25,'angles',0);
I get a totally different result (as expected). My question is, what is the effect of this parameter? I did not find in the manual or help what is that parameter.
Thanks
