scitex-linalg 0.1.2

Small linear-algebra helpers (distance, geometric median, cosine, nannorm) — standalone module from the SciTeX ecosystem

scitex-linalg

Small linear-algebra helpers extracted from the SciTeX ecosystem as a standalone package.

Install

pip install scitex-linalg            # core (numpy/scipy/sympy)
pip install "scitex-linalg[torch]"   # + geometric_median (torch + geom-median)

API

import scitex_linalg as sxl

sxl.euclidean_distance(u, v, axis=0)      # element-wise Euclidean distance
sxl.cdist(u, v)                           # pairwise distances
sxl.edist(u, v)                           # alias for cdist
sxl.cosine(v1, v2)                        # cosine similarity (NaN-safe)
sxl.nannorm(v, axis=-1)                   # NaN-aware vector norm
sxl.rebase_a_vec(v, v_base)               # project v onto v_base basis
sxl.three_line_lengths_to_coords(a, b, c) # triangle side lengths -> 2-D coords
sxl.geometric_median(xx, dim=-1)          # torch geometric median (requires [torch] extra)

Status

Standalone fork of scitex.linalg — intended to remain importable as scitex.linalg via the SciTeX umbrella package's bridge module. Decorators (numpy_fn, torch_fn, wrap) are vendored under _vendor_decorators/ to keep the package free of scitex.* runtime deps; when scitex-decorators is split out, those will be replaced with a direct dependency.
