Technical details

This package uses black for formatting and semver for versioning.

Usage

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.zeroes() or Matrix.identity(). You can also use random_matrix().

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.

Todo

• Add other linear algebraic operations
• Implement vectors
