The uniform apply-derivatives SamplingKind – the twin of t3toolbox.backend.fitting.apply_derivatives_kind().

Parameters:

  • x0_data (t3toolbox.backend.common.typ.Tuple)

  • order (int)

  • weight (t3toolbox.backend.common.typ.Optional[t3toolbox.backend.common.typ.Sequence[float]])

Return type:

SamplingKind
