polyhedra

✓ from passagemath_lrslib import polyhedra

✗ from passagemath.lrslib import polyhedra

Compute convex hull from a set of points and enumerate vertices.

from passagemath.lrslib import polyhedra # Define points (rows=points, columns=coordinates) points = [[0, 0], [1, 0], [0, 1], [1, 1]] # Compute convex hull vertices vertices = polyhedra.convex_hull(points) print(vertices) # Use environment variable for optional authentication if needed import os api_key = os.environ.get('PASSAGEMATH_API_KEY', '') # Not used in this example; included as placeholder.

Debug

Known issues

breakingpassagemath-lrslib is a replacement for SageMath's lrslib interface. Old imports like `from sage.geometry.polyhedron import Polyhedron` will not work.

fix

Use `from passagemath.lrslib import polyhedra` instead.

affects: >=10.0

gotchaThe `polyhedra` class expects points as a list of lists (rows=points, columns=coordinates). Transposing the matrix leads to incorrect results.

fix

Ensure your input matrix has shape (n_points, n_dimensions).

affects: all
