Convert inline function to sym in Matlab R2010b

I'm trying to convert an inline function to sym in matlab R2010b but it doesn't work. In matlab 2008 worked well. Here the code:

in = inline('t^2');
syms t real
sym(in);
??? Error using ==> sym.sym>tomupad at 2178
Conversion to 'sym' from 'inline' is not possible.

Error in ==> sym.sym>sym.sym at 111
                S.s = tomupad(x,'');

f0 = inline2sym(in);

EDU>> f0

t^2

EDU>> syms t
EDU>> diff(f0,t)

Instead of inline, you can use an anonymous function via a function handle:

f = @(t) t.^2;
syms t
F = sym(f);

which should give you the same inline functionality/portability.
