ConstantStep

class ConstantStep(*args)

Constant step.

Available constructors:

ConstantStep(epsilon=[1.0])

Parameters:

epsilonsequence of float

Finite difference steps for each dimension.

See also

BlendedStep

Notes

ConstantStep defines a list of constant finite difference steps equal to epsilon.

Examples

>>> import openturns as ot
>>> epsilon = [1e-4, 2e-4]
>>> steps = ot.ConstantStep(epsilon)
>>> print(steps([2.0]*2))
[0.0001,0.0002]
>>> print(steps([0.0, 3.0]))
[0.0001,0.0002]
