Labels Milestones New issue

Tracking: remove unregistered-dep workarounds once PureKLU + SparseColumnPivotedQR are registered; revisit Aqua tmax

CI/infra hardening: coverage upload, non-blocking nightly, CompatHelper, and a tracked benchmark suite

#16

One-shot structured `lstsq` over-allocates — post-hoc check matvecs and pivoted-QR Q materialization dominate

#15

· ChrisRackauckas-Claude opened

on May 31, 2026

Test coverage gaps: structured adjoint/matrix-RHS matvec, cached-LS value updates, and lstsq generic-eltype / guard boundary are untested

#14

`lstsq(alg=:iterative)` blanket-rejects non-BLAS eltypes, yet the iterative engine works in BigFloat

#13

· ChrisRackauckas-Claude opened

on May 31, 2026

Adjoint/transpose matvec allocates per call (forward path is alloc-free) — hurts the `:iterative` lstsq loop

#12

· ChrisRackauckas-Claude opened

on May 31, 2026

Precompile workload covers only the LU path — none of the QR / lstsq / adjoint surface is precompiled

#11

· ChrisRackauckas-Claude opened

on May 31, 2026

Add a LinearSolve algorithm that wraps `lstsq` — the LinearSolve extension cannot solve rank-deficient/inconsistent A

#10

· ChrisRackauckas-Claude opened

on May 31, 2026

Matrix-RHS adjoint/transpose matvec falls through to the generic dense fallback — ~3000x slowdown

#8

· ChrisRackauckas-Claude opened

on May 31, 2026

`SparseWithDenseRowColLeastSquares` has no fixed-pattern `refactor!` — the README's headline Newton-loop claim is currently false

#9

· ChrisRackauckas-Claude opened

on May 31, 2026

QR `refactor!` rebuilds the bordered matrix every call (~114 KB) instead of updating values in place — fix the advertised hot path
