step function: the limit of a sigmoid. 0 before BasisFunction.Center, 1 afterwards, with a transition sharpness controlled by BasisFunction.Scale.
Step
00 Remarks
Models an instantaneous state change (fuse blowing, threshold alarm). When BasisFunction.Scale > 0 it uses a logistic sigmoid for a smooth-but-sharp transition; when Scale = 0 it becomes an exact Heaviside step.
