General code for the Equivariant Filter (EqF) in Python3. The automatic EqF uses numerical differentiation to minimise the work involved in implementing an equivariant filter. Of course, for analytic derivatives are preferred for applications where speed is important, but the automatic EqF framework facilitates fast and easy prototyping.

In order to run the code, the following dependencies are required.

• NumPy: pip install numpy
• pylie: https://github.com/pvangoor/pylie
• Matplotlib: (for the example) pip install matplotlib
