Module truncation 

Truncation policy types for decomposition algorithms.

This module keeps algorithm selection separate from algorithm-specific truncation semantics. SVD-based routines use SvdTruncationPolicy, while QR and other decompositions keep their own option types.

Structs

InvalidThresholdError

Error for invalid SVD truncation thresholds.

SvdTruncationPolicy

Explicit truncation policy for SVD-based decompositions.

Enums

DecompositionAlg

Decomposition/factorization algorithm.

SingularValueMeasure

Singular-value-derived quantity used for truncation.

SvdTruncationOptionsError

Error from validating optional SVD truncation options.

ThresholdScale

Threshold scaling for SVD truncation.

TruncationRule

Rule used to map singular values to a retained rank.

Functions

validate_svd_truncation_options

Validate optional SVD truncation options shared by all callers.
