- Purpose
Given a collection of vectors enforces for each vector that
either all its components are equal to 0,
or all its components are different from 0.
In addition imposes that at least one 0 is used.
- Example
-
The constraint holds since:
Both components of the first vector are different from 0.
Both components of the second vector are different from 0.
Both components of the third vector are equal to 0.
Both components of the fourth vector are different from 0.
Both components of the fifth vector are equal to 0.
