Set-theoretical universe

MuPAD® notebooks will be removed in a future release. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.


universe represents the set-theoretical universe of all objects.

universe is the only element of the domain stdlib::Universe.

The standard set operations such as union, intersection and subtraction can be used with universe.


Example 1

We show some basic set operations involving universe:

universe union {a}

universe intersect {a}

{a} minus universe
