Public Member Functions
	Expr_NamedFunction (const TCollection_AsciiString &name, const Handle< Expr_GeneralExpression > &exp, const Expr_Array1OfNamedUnknown &vars)
	Creates a function of given variables <vars> with name <name> defined by the expression <exp>.
void	SetName (const TCollection_AsciiString &newname)
	Sets the name <newname> to <me>.
TCollection_AsciiString	GetName () const
	Returns the name assigned to <me>
Standard_Integer	NbOfVariables () const
	Returns the number of variables of <me>.
Handle_Expr_NamedUnknown	Variable (const Standard_Integer index) const
	Returns the variable denoted by <index> in <me>. Raises OutOfRange if <index> is greater than NbOfVariables of <me>, or less than or equal to zero.
Standard_Real	Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &values) const
	Computes the value of <me> with the given variables. Raises DimensionMismatch if Length(vars) is different from Length(values).
Handle_Expr_GeneralFunction	Copy () const
	Returns a copy of <me> with the same form.
Handle_Expr_GeneralFunction	Derivative (const Handle< Expr_NamedUnknown > &var) const
	Returns Derivative of <me> for variable .
Handle_Expr_GeneralFunction	Derivative (const Handle< Expr_NamedUnknown > &var, const Standard_Integer deg) const
	Returns Derivative of <me> for variable with degree <deg>.
Standard_Boolean	IsIdentical (const Handle< Expr_GeneralFunction > &func) const
	Tests if <me> and <func> are similar functions (same name and same used expression).
Standard_Boolean	IsLinearOnVariable (const Standard_Integer index) const
	Tests if <me> is linear on variable on range <index>
TCollection_AsciiString	GetStringName () const
Handle_Expr_GeneralExpression	Expression () const
	Returns equivalent expression of <me>.
void	SetExpression (const Handle< Expr_GeneralExpression > &exp)
	Modifies expression of <me>. Warning: Beware of derivatives. See FunctionDerivative
