deferred class MultipleVarFunctionWithGradient from math
|
|
|
|
inherits MultipleVarFunction
|
|
---Purpose:
|
|
-- The abstract class MultipleVarFunctionWithGradient
|
|
-- describes the virtual functions associated with a multiple variable function.
|
|
uses Vector from math
|
|
|
|
is
|
|
|
|
Delete(me:out) is virtual;
|
|
---C++: alias "Standard_EXPORT virtual ~math_MultipleVarFunctionWithGradient(){Delete();}"
|
|
|
|
NbVariables(me)
|
|
---Purpose: Returns the number of variables of the function.
|
|
|
|
returns Integer
|
|
is deferred;
|
|
|
|
|
|
Value(me: in out; X: Vector; F: out Real)
|
|
---Purpose: Computes the values of the Functions <F> for the variable <X>.
|
|
-- Returns True if the computation was done successfully,
|
|
-- False otherwise.
|
|
|
|
returns Boolean
|
|
is deferred;
|
|
|
|
|
|
Gradient(me: in out; X: Vector; G: out Vector)
|
|
---Purpose: Computes the gradient <G> of the functions for the variable <X>.
|
|
-- Returns True if the computation was done successfully,
|
|
-- False otherwise.
|
|
|
|
returns Boolean
|
|
is deferred;
|
|
|
|
|
|
Values(me: in out; X: Vector; F: out Real; G: out Vector)
|
|
---Purpose: computes the value <F> and the gradient <G> of the
|
|
-- functions for the variable <X>.
|
|
-- Returns True if the computation was done successfully,
|
|
-- False otherwise.
