pawaer / matrixmath

Python package for matrix caclulations. Exercise for writing own package.

Matrix Math

Providing simple Matrix functionalities such as multiplication

Disclaimer

Just Multiplication implemented! Unlikely that it gets further developed. It just serves as a first simple try on writing own python packages

Due to using float values the resulting values can have a small deviation In a real project numpy would be used. This is just a training repository.

Purpose

This repository serves as a training project for the author with python packages

How to use

from matrixmath import Matrix, EvenMatrix, Multiplication
matrix1 = Matrix (23, 24, -109) # 23 rows, 24 columns initialized with -109
matrix2 = EvenMatrix (3, 13) # 3 rows, 3 colums, initialized with 13
Multiplication().operate(matrix1, matrix2) # will fail. Raises Value error
matrix3 = EvenMatrix (3, 7)
matrix2.setValue(0, 0, -3)
matrix2.setValue(0, 1, 3) # cell at row 0, column 1 changed to value 3 
matrix2.setValue(0, 2, 1)
matrix2.setValue(1, 0, -2)
matrix2.setValue(1, 1, -3)
matrix2.setValue(1, 2, 1)
matrix2.setValue(2, 0, 0.1)
matrix2.setValue(2, 1, -2)
matrix2.setValue(2, 2, 1)
matrixResult = Multiplication().operate(matrix2, matrix3)
print(matrix1)
print(matrix2)
print(matrix3)
print(matrixResult)
