About this pip-installable source distribution

This pip-installable source distribution sagemath-modules is a distribution of a part of the Sage Library. It provides a small subset of the modules of the Sage library (“sagelib”, sagemath-standard).

What is included

• Vectors, Vector Spaces, Modules

• Matrices and Spaces of Matrices

• Fields of real and complex numbers in arbitrary precision floating point arithmetic (using MPFR, GSL, mpmath, MPC)

• Free Modules with Combinatorial Bases

• Tensor Modules

• Additive Abelian Groups

• Matrix and Affine Groups

• Root Systems

• Quadratic Forms

• Ring Extensions and Derivations

• Clifford, Exterior, and Weyl Algebras

• Chain Complexes, Homology, Free Resolutions

• Matroid Theory

• Coding Theory

• Cryptography

• Probability Spaces and Distributions, Statistics

Examples

A quick way to try it out interactively:

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-modules[test]" ipython

In [1]: from sage.all__sagemath_modules import *

In [2]: M = matroids.Wheel(5); M
Out[2]: Wheel(5): Regular matroid of rank 5 on 10 elements with 121 bases

In [3]: M.representation()
Out[3]:
