MATLAB Live scripts for Physics and Finance

The live scripts (with file extension .mlx) are specially prepared MATLAB files that contain text explanations, images as well as executable MATLAB code. Just load them from your MATLAB installation. You can also look at a webpage online (well, not from within github, but otherwise it looks fine. It is the html that MATLAB generated) or download a pdf. Both are automatically generated from the running live script and contain everything, input as well as output, including plots.

My book Physics and Finance was published by Springer in March 2021 as part in the Series of Undegraduate Lecture Notes in Physics. The German translation was published in October 2023.
