Sym and Syms matlab 2014b MAC doesn't exist

Well, the title basically tells everything. I have Matlab version 2014b for MAC, and I want to declare a variable or a matrix using the command sym or syms as I did in preview versions, but this time I get the following error message:

>> syms a Undefined function 'syms' for input arguments of type 'char'.

>> x=sym('x'); Undefined function 'sym' for input arguments of type 'char'.

So.... help! =/ please ! ! !

Hi Mischa, my problem is the some that the other person in the question that you send me. So, I have the license "ans=1" but there is not in the list. so What can I do to have it? :/

It sounds as if you are licensed for it but have not installed it. You might not have selected it for installation when you went through the installation procedure.
