uniform_probe_kind#

t3toolbox.backend.uniform_fitting.uniform_probe_kind(x0_data, weight=None)#
def uniform_probe_kind(
        x0_data:  typ.Tuple,
        weight:   typ.Optional[typ.Any] = None,  # per-mode residual weight ω, (d,) / (d,1); None = 1
) -> bfit.SamplingKind:        # the uniform vector-valued `probe` sampling kind (optionally per-mode weighted)

The uniform probe SamplingKind – the twin of t3toolbox.backend.fitting.probe_kind().

The forward / residual are the packed probe output (d,)+W+C+(N,) (mode index d at axis 0, no order axis), so the per-mode weight ω is built with mode_axis=0 (no order axis) and sumsq / transpose are overridden to weight it (ω enters sumsq ×ω, transpose ×ω²).

Parameters:

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

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

Return type:

SamplingKind
