FiniteDifferenceStep

class FiniteDifferenceStep(*args)

Base class to define finite difference steps.

Available constructors:

FiniteDifferenceStep(epsilon=[1.0])

Parameters

epsilonsequence of float

Finite difference steps for each dimension.

Notes

Base class to define how finite difference steps are computed. Using FiniteDifferenceStep is equivalent to use its derived class ConstantStep. Another way to compute steps is through its second derived class BlendedStep.

Methods

__call__(inP)	Call self as a function.
getClassName()	Accessor to the object’s name.
getEpsilon()	Get the finite difference steps.
getId()	Accessor to the object’s id.
getImplementation()	Accessor to the underlying implementation.
getName()	Accessor to the object’s name.
setEpsilon(epsilon)	Set the finite difference steps.
setName(name)	Accessor to the object’s name.

__init__(*args)

Initialize self. See help(type(self)) for accurate signature.

getClassName()

Accessor to the object’s name.

Returns

class_namestr

The object class name (object.__class__.__name__).

getEpsilon()

Get the finite difference steps.

Returns

epsilonPoint

If ConstantStep : Finite difference steps for each dimension.

If BlendedStep : Finite difference step factors for each dimension.

getId()

Accessor to the object’s id.

Returns

idint

Internal unique identifier.

getImplementation()

Accessor to the underlying implementation.

Returns

implImplementation

The implementation class.

getName()

Accessor to the object’s name.

Returns

namestr

setEpsilon(epsilon)

Set the finite difference steps.

Parameters

epsilonsequence of float

If ConstantStep : Finite difference steps for each dimension.

If BlendedStep : Finite difference step factors for each dimension.

setName(name)

Accessor to the object’s name.

Parameters

namestr

The name of the object.
