@AmenZwa I am not immediately seeing how to turn this into a PDF; do you know how, or whether it is purely intended to be an HTML book? I wouldn't think so, given the existence of 'toc1.pdf', but I'm a bit at sea. I also see that it says that matlab is required to regenerate at least book 1's figures, but at least they are present as PNGs. Still that makes me nervous.
