PyFinitDiff is a robust Python package designed to compute finite-difference matrices with an intuitive API. This package provides an efficient and user-friendly interface for generating finite-difference approximations, making it ideal for numerical analysis and scientific computing.
Features
Intuitive API: PyFinitDiff offers an easy-to-use interface that allows users to generate finite-difference matrices with minimal effort.
Versatile Applications: Suitable for a wide range of numerical methods including solving partial differential equations (PDEs), performing numerical differentiation, and more.
Comprehensive Documentation: Detailed documentation and examples to help users get started quickly.
Installation
PyFinitDiff requires Python 3.10+ and is available on PyPi for various operating systems including Linux and macOS.
Install PyFinitDiff via pip:
pip install PyFinitDiffDocumentation

Usage Example
Below is a simple example to illustrate how to use PyFinitDiff:
from PyFinitDiff.finite_difference_1D import FiniteDifference
from PyFinitDiff.finite_difference_1D import Boundaries
boundaries = Boundaries(left='none', right='none')
n_x = 100
fd = FiniteDifference(
n_x=n_x,
dx=1,
derivative=2,
accuracy=2,
boundaries=boundaries
)
fd.triplet.plot()
dense_matrix = fd.triplet.to_scipy_sparse()
sparse_matrix = fd.triplet.to_scipy_sparse()This would produce the following figure:
This example demonstrates the creation of a second-order finite-difference matrix with a specified grid spacing and size.
Testing
To test PyFinitDiff locally, clone the GitHub repository and run the tests with coverage:
