source: build-install/usr/lib/python3.14/site-packages/scipy/interpolate/_bsplines.py:2428

Signature

def _lsq_clamp_preprocess(A, offset, nc, k, y_w, ci, cf, x, y, w)

Summary

Apply the clamp preprocessing to packed matrix + RHS for the QR path.

Extended Summary

Adjusts y_w for the pinned coefficients, reduces (A, offset, nc) by dropping boundary rows and dense columns 0 and nc-1, and returns everything ready to feed into qr_reduce + fpback.
