A simple linear algebra package written in vanilla python3
Installation can be done through
pip. You must have python version >= 3.6.
pip install linalg
Docs can be found at the readthedocs page
What is this?
NOT intended to be the best or fastest.
NOT intended to be production-grade (yet).
IS intended to be fully vanilla python3.
IS meant as an educational tool.
This package uses black for formatting and semver for versioning.
This package provides the
Matrix class and utility functions.
import linalg from linalg import * # import the Matrix class and utility functions top-level from linalg import Matrix # import the Matrix class
To create a matrix object, initialize it with a 2D list or use
Matrix.identity(). You can also use
mat = linalg.Matrix([[3, 4, 5], [2, 5, -1], [0, 2, 1]]) # 3x3 matrix mat = linalg.as_matrix([[3, 4, 5], [2, 5, -1], [0, 2, 1]]) # 3x3 matrix, alternative notation mat = linalg.zeroes(4, 2) # 4x2 zero matrix mat = linalg.identity(4) # 4x4 identity matrix mat = linalg.random_matrix((2, 3), (-10, 10)) # 2x3 matrix with elements within (-10, 10)
This package implements matrix multiplication with the python matrix multiplication operator
__matmul__). The matrix multiplication of two
linalg.Matrix A, B is
C = A @ B.
After that, you can use multiple functions to perform linear algebraic operations as explained in the above linked docs.
- Add other linear algebraic operations
- Implement vectors
- Add documentation
