• 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.
Interval constraints take the form of one or
more inequalities joined by logical “and” or
“or” operators. Interval constraints also
permit simplification that otherwise might
be invalid or not computable.
Exclusions use the “not equals” (/= or ≠)
relational operator to exclude a specific
value from consideration.

Value → Var
List → Var
Matrix → Var
Expr → Function(Param1,...)
List → Function(Param1,...)
Matrix → Function(Param1,...)
If the variable Var does not exist, creates it
and initializes it to Value, List, or Matrix.
If the variable Var already exists and is not
locked or protected, replaces its contents
with Value, List, or Matrix.
