Module cls 

Constrained least-squares (CLS) active-set solver and problem formulations.

Solver

solve and solve_cls solve min ‖Au − b‖² subject to umin ≤ u ≤ umax using an active-set method with incremental QR updates via Givens rotations.

Problem formulations

Module	Formulation	A size
setup::wls	Weighted LS with regularisation	(NV+NU) × NU
setup::ls	Plain LS (no regularisation)	NV × NU

Modules

linalg

Low-level linear algebra: Householder QR, back-substitution, constraint checking. Shared linear algebra utilities: constraint checking, Householder QR, and triangular back-substitution.

setup

Problem formulations (WLS, unreg LS). Problem formulation: convert domain parameters into min ‖Au − b‖² form.

solver

Active-set constrained least-squares solver.

types

Core types, constants, and nalgebra type aliases. Types for the constrained least-squares solver.
