This is the lintrans project. It is a Python package with a GUI. This project aims to provide an
easy way to visualize matrices as linear transformations. The user can define 2x2 matrices and
visualize them in 2D space. The user can also visualize compositions of defined matrices - addition
and multiplication - as well as inverses and transpositions.
This program is aimed at teachers teaching linear transformations, as well as students learning it for the first time. The 3blue1brown series Essence of Linear Algebra is a fantastic learning resource for this topic and I aim to provide an interactive supplement to that series.
The Python source code can be found in src/lintrans/ and the full documentation can be found on
readthedocs.io. I highly recommend reading the full
tutorial.
This project is also my A Level Computer Science NEA (Non-Exam Assessment), which means I need to
provide a write-up of the development process. This write-up is written in LaTeX and can be found
in the write-up branch. The compiled
PDF can also be downloaded from my GitHub pages site.
I recommend downloading a pre-built executable file from the releases page.
You can also run the package directly by installing it in a virtual environment with pip install -e . and then running python -m lintrans.
Compiling the package from source is also an option. Instructions are available here.

Open source contributions are sadly not open at this time, because this is a school project, which means I need to do it on my own. If you want to contribute to this project and make it better in the future, just email me and I'll notify you when I can open the project to other contributors.
