Filter Simulation Toolkit for Education

Kalman Filter Simulation Tutorials

This project is the reorganization of the code in the book Kalman-and-Bayesian-Filters-in-Python and draws on some content in EKF/UKF Toolbox for MATLAB.

Goals

• Provide a set of easy-to-understand introductory tutorials
• Build a filter simulation toolkit that is friendly to beginners

Requirements

To build the environment, there are 3 options

• Install Anaconda
• Install Miniconda
• Install Miniforge

For option 2&3, you need to run the following command after installation

conda install matplotlib pandas scipy sympy jupyterlab

Then, clone this repo

git clone https://github.com/ivaquero/blog-filters.git

Finally, launch jupyterlab to run the code

cd [this repo] && jupyter lab
