Module common 

Shared machinery for fitters.

Every fitter operation is a contraction of a stored matrix with one axis of a column-major tensor. The tensor is addressed as [pre, n, post], where pre is the product of the extents before the target axis and post the product of those after it, so no data movement is needed to bring the target axis to the front.

This module provides the InplaceFitter trait, layout validation for tenferro tensors and views, and the SVD-based least-squares factors.

Traits

FitScalar

f64 or Complex<f64>, viewable as interleaved f64 storage.

InplaceFitter

Evaluation and fitting along one axis of an N-dimensional tensor, writing into a caller-provided output view.

SvdScalar

Scalars with an SVD through tenferro-linalg.

Functions

singular_values

Singular values of a contiguous column-major n x m matrix, descending.
