N_

Positive integers

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.

Description

N_ represents the set of positive integers.

The four basic sets are assigned to the identifiers Z_, Q_, R_, and C_ during system initialization.

The set of positive integers, too, is assigned to the identifier N_ during system initialization. It is not represented by a basic set but by the intersection of Z_ and the interval Dom::Interval([1], infinity).
