FiniteDifferenceStep

class FiniteDifferenceStep(*args)

Base class to define finite difference steps.

Available constructors:

FiniteDifferenceStep(epsilon=[1.0])

Parameters:

epsilon : sequence 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.

__init__(*args)

x.__init__(…) initializes x; see help(type(x)) for signature

getClassName()

Accessor to the object’s name.

Returns:

class_name : str
