cd mjurav-DE2.1
poetry install

Install as a package from PyPi

Navigate to your project where you want to have mjurav-DE2.1 package as a dependency, and use poetry add command:

poetry add mjurav-de2-1

Usage

Transposing a 2D Matrix

To transpose a 2D matrix, use the transpose2d function from src/data_transformation/transform.py.

from data_transformation.transform import transpose2d

matrix = [[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]]
transposed_matrix = transpose2d(matrix)
print(transposed_matrix)

Generating Windows from a 1D Array

To generate windows from a 1D array, use the window1d function from src/data_transformation/transform.py.

from data_transformation.transform import window1d

array = [1, 2, 3, 4, 5]
windows = window1d(array, size=2, shift=1, stride=1)
print(windows)

Applying 2D Convolution

To apply a 2D convolution operation, use the convolution2d function from src/data_transformation/transform.py.

import numpy as np
from data_transformation.transform import convolution2d

input_matrix = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
kernel = np.array([[1, 0], [0, -1]])
convolved_matrix = convolution2d(input_matrix, kernel)
print(convolved_matrix)

Running Tests

To run the tests, use the following command:

poetry run python -m unittest tests/test_functions.py
