| (constraint operator)
/k keys
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. They are used
primarily to exclude an exact solution when
using cSolve(), cZeros(), fMax(), fMin(),
solve(), zeros(), and so on.

Expr → Var
List → Var
Matrix → Var
Expr → Function(Param1,...)
List → Function(Param1,...)

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