You need to reach in to the Symbolic engine and use the facilities of MuPAD that are not made available to the MATLAB interface.

http://www.mathworks.com/help/symbolic/mupad_ref/dom-interval.html

For example,

x = evalin(symengine, 'Dom::Interval([0], [3])');

The mean of this certainly would be the same as mean(0:3) and the same as mean(linspace(0,3,50000)) .
