context | ctx

Build a multitape context from contexts by tupling the labelsets (i.e., going multitape), and joining the weightsets (i.e., looking for a common support if they are different).

See also:

• automaton.tuple
• expression.tuple
• polynomial.tuple

Examples

import vcsn
vcsn.context('lal(ab), q') | vcsn.context('lan(xy), r')

$\{a, b\} \times (\{x, y\})^?\to\mathbb{R}$
