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 |
