alumath-group20 0.1.0

A library for matrix operations by Group 20

alumath_group20 : A Python library for matrix operations, supporting multiplication of matrices with different dimensions, developed by Group 20: Christian, Carine, Eva, and Thierry.

Installation

Install via pip: pip install alumath_group20

Usage The alumath_group20 library, created by Christian, Carine, Eva, and Thierry, provides a Matrix class for matrix multiplication with compatible dimensions.

Below are examples: Example 1: Multiplying Two 2x2 Matrices

from alumath_group20 import Matrix

Define two 2x2 matrices

A = Matrix([[1, 2], [3, 4]]) B = Matrix([[5, 6], [7, 8]])

Multiply using @

C = A @ B print("2x2 * 2x2 Matrix:") print(C)

Output: 2x2 * 2x2 Matrix: 19 22 43 50

Example 2: Multiplying a 2x3 Matrix by a 3x2 Matrix from alumath_group20 import Matrix

Define a 2x3 and a 3x2 matrix

X = Matrix([[1, 2, 3], [4, 5, 6]]) Y = Matrix([[7, 8], [9, 10], [11, 12]])

Multiply

Z = X @ Y print("2x3 * 3x2 Matrix:") print(Z)

Output: 2x3 * 3x2 Matrix: 58 64 139 154

Example 3: Handling Incompatible Dimensions from alumath_group20 import Matrix

Define incompatible matrices (1x2 and 3x1)

A = Matrix([[1, 2]]) B = Matrix([[1], [2], [3]])

try: C = A @ B except ValueError as e: print(e)

Output (member name varies): Matrix dimensions incompatible for multiplication, says Christian, Carine, Eva, or Thierry(name is picked randomly)

Notes :

Supports multiplication for compatible dimensions (m×n * n×p = m×p). For incompatible dimensions, raises ValueError with a message including a randomly selected member (Christian, Carine, Eva, or Thierry). Uses the @ operator for multiplication.
