I am certainly interested in Lua Maths libraries, and I assume by
Maths you mean broad coverage such as in GNU Scientific Library.

Re cephes, this one looks interesting:

https://github.com/deepmind/torch-cephes

However it relies on LuaJIT FFI. Facebook does have an FFI module that
says it works with Lua 5.3 (https://github.com/facebook/luaffifb) but
I haven't tested it.

In your criteria - are you only considering libraries that work with Lua 5.3?
