Public Member Functions | |
Expr_PolyFunction (const Handle< Expr_GeneralFunction > &func, const Expr_Array1OfGeneralExpression &exps) | |
Creates <me> as <func>(<exps_1>,<exps_2>,...,<exps_n>) | |
Handle_Expr_GeneralFunction | Function () const |
Returns the function defining <me>. | |
Handle_Expr_GeneralExpression | ShallowSimplified () const |
Returns a GeneralExpression after a simplification of the arguments of <me>. | |
Handle_Expr_GeneralExpression | Copy () const |
Returns a copy of <me> having the same unknowns and functions. | |
Standard_Boolean | IsIdentical (const Handle< Expr_GeneralExpression > &Other) const |
Tests if <me> and <Other> define the same expression. This method does not include any simplification before testing. | |
Standard_Boolean | IsLinear () const |
Tests if <me> is linear on every NamedUnknown it contains. | |
Handle_Expr_GeneralExpression | Derivative (const Handle< Expr_NamedUnknown > &X) const |
Returns the derivative on <X> unknown of <me> | |
Standard_Real | Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &vals) const |
Returns the value of <me> (as a Real) by replacement of <vars> by <vals>. Raises NotEvaluable if <me> contains NamedUnknown not in <vars> or NumericError if result cannot be computed. | |
TCollection_AsciiString | String () const |
returns a string representing <me> in a readable way. |
