Error using fitdist. Distribution name 'multinomial' is unrecognized.

I am using 2015b. I read http://uk.mathworks.com/help/stats/fitdist.html and see that it supports "multinomial"
I run
pd = makedist('Multinomial','probabilities',[1/2 1/3 1/6])
pd =
MultinomialDistribution
Probabilities:
0.5 0.33333 0.16667
Then I run
fitdist([1 10]','normal')
ans =
NormalDistribution
Normal distribution
mu = 5.5 [-51.6779, 62.6779]
sigma = 6.36396 [2.83928, 203.075]
Then I try and run
fitdist([1 10]','multinomial')
Error using fitdist (line 146)
Distribution name 'multinomial' is unrecognized.
I do not understand why. Please advise.

I believe that this may be a documentation error. If you actually look inside the fitdist function, using
edit fitdist
you'll see that 'Multinomial' is not in the list of supported distributions. (But 'Kernel' is not there either, and actually does work.)
Weird. You might want to report to support@mathworks.
