I just came across this very nice webpage which has a lot of very nicely typeset math (for a webpage):

[“The Matrix Calculus You Need For Deep Learning”](http://parrt.cs.usfca.edu/doc/matrix-calculus/index.html)

Turns out they have their own system for moving from math-heavy markdown to HTML or LaTeX: [bookish](https://github.com/parrt/bookish) (“Bookish – math-infested markdown to HTML and latex”)

I know everyone wants an HTML version of the manual. Maybe this tool could help?

I’m pretty happy with bookdown—the formats are way better than all the knitr formats other than the Tufte format. I really like the latter, which I used for my latest case study:

[http://mc-stan.org/users/documentation/case-studies/lotka-volterra-predator-prey.html](http://mc-stan.org/users/documentation/case-studies/lotka-volterra-predator-prey.html)

If I were starting from scratch, I’d almost certainly use that. As is, I think it’ll be a bit easier and more natural to move to bookdown.

The basic bookdown tex output is pretty basic, and apparently so is this new tools’:

The Tufte format LaTeX output is beautiful.
