One of the most important aspects of scientific work is reproducibility. Indeed, many journals encourage authors to make their publications reproducible by publishing the underlying code on a website. Unfortunately, this important aspect is often neglected. It is therefore very hard, sometimes even impossible, to reproduce certain results. This unfortunate situation should be changed. To set a good example, some of my papers are supported by a downloadable Matlab/Python code. All figures from those papers can be reproduced. More than 1300 downloads within one year from https://www.nt.tuwien.ac.at/downloads/ and approximately 250 unique visitors per month at GitHub show that this is well received within the community.
