Expr_FunctionDerivative (const Handle< Expr_GeneralFunction > &func, const Handle< Expr_NamedUnknown > &withX, const Standard_Integer deg) | |
Creates a FunctionDerivative of degree <deg> relative to the <withX> variable. Raises OutOfRange if <deg> lower or equal to zero. | |
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> greater than NbOfVariables of <me>. | |
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> | |
Handle_Expr_GeneralFunction | Function () const |
Returns the function of which <me> is the derivative. | |
Standard_Integer | Degree () const |
Returns the degree of derivation of <me>. | |
Handle_Expr_NamedUnknown | DerivVariable () const |
Returns the derivation variable of <me>. | |
