The constraint (“|”) symbol serves as a
binary operator. The operand to the left of |
is an expression. The operand to the right of
| specifies one or more relations that are
intended to affect the simplification of the
expression. Multiple relations after | must
be joined by logical “and” or “or” operators.
The constraint operator provides three basic
types of functionality:
• Substitutions
• Interval constraints
• Exclusions
Substitutions are in the form of an equality,
such as x=3 or y=sin(x). To be most
effective, the left side should be a simple
variable. Expr | Variable = value will
substitute value for every occurrence of
Variable in Expr.
