I was reading this article (https://www.nature.com/articles/srep40083) about designing a panoramic lens with transformation optics, and wanted to try to play around with modifying the coordinate transformations. I contacted one of the authors of the article, and she mentioned that she plotted the coordinate transformations in Matlab, creating this image (Figure 3 in the article):(adsbygoogle = window.adsbygoogle || []).push({});

However, I can't seem to figure out how the authors made these graphs.

These were the equations used:

What is the process for plotting coordinate transformations like these? I'm new to Matlab and don't really know where to start.
