CHAR-POL

In this repository we provide the implementation of the project "Computing the characteristic polynomial" of the class Computational Linear Algebra, MATH-453
Authors: Anna Paulish, Fabio Matti

Instructions

You can reproduce our results with

git clone https://github.com/FMatti/CHAR-POL.git
cd CHAR-POL
python main.py

If dependency problems arise, you can mirror our Python environment using

python -m venv .venv

source .venv/bin/activate   # on Linux, macOS
.venv\Scripts\activate.bat  # in Windows command prompt (recommended)
.venv\Scripts\Activate.ps1  # in Windows PowerShell

python -m pip install --upgrade pip
python -m pip install -r requirements.txt

Our implementations require a Python version $\geq$ 3.8.

File structure

Our implementations are located in the src/ directory. Our results can be found in the Jupyter notebook main.ipynb or equivalently reproduced by running the Python script main.py.
