A library for matrix operations with Fraction support

MATRIX OPERATIONS LIBRARY

This is a Python library that provides functionality to perform basic matrix operations and convert matrices to Reduced Row Echelon Form (RREF). The library supports operations with fractions to maintain precision in calculations.

FEATURES

• Create and manipulate matrices
• Add, subtract, multiply, and divide matrices
• Swap rows of a matrix
• Convert a matrix to Reduced Row Echelon Form (RREF)
• Perform operations using fractions (fractions.Fraction) for accurate results

REQUIREMENTS

• Python 3.7 or later
• The library depends on Python's built-in fractions.Fraction for precise fractional arithmetic.

INSTALLATION

To install this library, clone this repository:

git clone https://github.com/ArturZZerg/matrix.git

Once cloned, install any necessary dependencies:

pip install -r requirements.txt

If you're using fractions in your code, ensure that you have Python's fractions module available, which comes by default with Python installations.

USAGE

Here's an example of how to use the library:

from matrix import Matrix,calc_matrix

# Create a matrix using a two-dimensional list
A = Matrix([[1, 2], [3, 4]])

# Convert to RREF
calc_matrix(A)
print(A)

MATRIX CLASS METHODS

Initialization

Matrix(matrix: list[list[float]])

Initialize the matrix with a 2D list of numbers.

Basic Operations

• rows in matrix starts from 1.
• add_trans(self, r1, r2, mult=None): Adds. r1(row number) += r2(row number)*mult
• sub_trans(self, r1, r2, mult=None): Subtracts. r1(row number) -= r2(row number)*mult.
• mult_trans(self,r, mult): Multiplies r(row number)+=mult.
• div_trans(matrix: Matrix): Divides r(row number)/=mult.
• swap_trans(row1: int, row2: int): Swaps two rows of the matrix.

RREF Conversion

• calc_matrix("matrix"): Converts the matrix to Reduced Row Echelon Form.
