ConstantStep¶
- class ConstantStep(*args)¶
Constant step.
- Parameters:
- epsilonsequence of float
Finite difference steps for each dimension.

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]
