deferred class FunctionWithDerivative from math
|
|
---Purpose:
|
|
-- This abstract class describes the virtual functions associated with
|
|
-- a function of a single variable for which the first derivative is
|
|
-- available.
|
|
|
|
inherits Function
|
|
|
|
is
|
|
|
|
Delete(me:out) is virtual;
|
|
---C++: alias "Standard_EXPORT virtual ~math_FunctionWithDerivative(){Delete();}"
|
|
|
|
Value(me: in out; X: Real; F: out Real)
|
|
---Purpose: Computes the value <F>of the function for the variable <X>.
|
|
-- Returns True if the calculation were successfully done,
|
|
-- False otherwise.
|
|
|
|
returns Boolean
|
|
is deferred;
|
|
|
|
Derivative(me: in out; X: Real; D: out Real)
|
|
---Purpose: Computes the derivative <D> of the function
|
|
-- for the variable <X>.
|
|
-- Returns True if the calculation were successfully done,
|
|
-- False otherwise.
|
|
|
|
returns Boolean
|
|
is deferred;
|
|
|
|
Values(me: in out; X: Real; F, D: out Real)
|
|
---Purpose: Computes the value <F> and the derivative <D> of the
|
|
-- function for the variable <X>.
|
|
-- Returns True if the calculation were successfully done,
|
|
-- False otherwise.
