pdegplot 'Too many input arguments.' when trying to show edge labels

Hi, I am trying to show the edge labels of a geometry with pdegplot, but I always get the same error: "Too many input arguments." Even if I try to run the example given in the pdegplot documentation I get the error. The example ist the following:

g = [2  1  1  1  1  1  1  1  1  4  4;
-1  -0.55  -0.5  -0.45  -0.5  0.45  0.5  0.55  0.5  -1  0.169101978725763;
1  -0.5  -0.45  -0.5  -0.55  0.5  0.55  0.5  0.45  0.169101978725763  1;
0  -0.25  -0.3  -0.25  -0.2  -0.25  -0.3  -0.25  -0.2  0  -0.739198919740117;
0  -0.3  -0.25  -0.2  -0.25  -0.3  -0.25  -0.2  -0.25  -0.739198919740117  0;
0  0  0  0  0  0  0  0  0  1  1;
1  1  1  1  1  1  1  1  1  0  0;
0  -0.5  -0.5  -0.5  -0.5  0.5  0.5  0.5  0.5  0  0;
0  -0.25  -0.25  -0.25  -0.25  -0.25  -0.25  -0.25  -0.25  0  0;
0  0.05  0.05  0.05  0.05  0.05  0.05  0.05  0.05  1  1;
0  0  0  0  0  0  0  0  0  0.75  0.75;
0  0  0  0  0  0  0  0  0  0  0];
pdegplot(g)

pdegplot(g,'edgeLabels','on','subdomainLabels','on')
ylim([-.8,.1]) % to see the top edge clearly

pdegplot(g) works fine, but as soon as I give the additional arguments, I get the error. I can't really figure out why so it would be great if somebody could help me with that. I am using Matlab R2012a.

Best Regards

The labeling functionality is new in R2012b.
