Public Member Functions | |
Expr_Sum (const Expr_SequenceOfGeneralExpression &exps) | |
Creates the sum of all the members of sequence <exps>. | |
Expr_Sum (const Handle< Expr_GeneralExpression > &exp1, const Handle< Expr_GeneralExpression > &exp2) | |
Creates the sum of <exp1> and <exp2>. | |
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>. | |
virtual Handle_Expr_GeneralExpression | NDerivative (const Handle< Expr_NamedUnknown > &X, const Standard_Integer N) const |
Returns the <N>-th derivative on <X> unknown of <me>. Raises OutOfRange if <N> <= 0 | |
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. |
