gauss-jacobi-quad 0.2.2

CPython extension for GaussJacobiQuad (ISO_C_BINDING C ABI, Stable ABI / abi3)

gauss-jacobi-quad

CPython extension for GaussJacobiQuad.

• Calls ISO_C_BINDING entry gauss_jacobi_rule_c (same ABI as the C library)
• Stable ABI (Py_LIMITED_API 3.9 → one cp39-abi3 manylinux wheel for 3.9+)
• Multi-phase module init (PEP 489)
• Heap exception type via PyErr_NewException (dynamic type)
• Wheel embeds the Fortran/C kernels (meson-python + gfortran)

Free-threaded CPython (3.13t) is a different ABI and does not load abi3 wheels; use a from-source build there if needed.

Install

pip install gauss-jacobi-quad

Building from source requires gfortran, openblas/lapack, meson, ninja.

Usage

from gauss_jacobi_quad import gauss_jacobi, GaussJacobiError

x, w = gauss_jacobi(32, 0.0, 0.0)                 # auto
x, w = gauss_jacobi(40, 0.5, 0.5, method="glr")

No GJP_CINTERP needed for the extension wheel.
