Jackalope / jmath (public) (License: GPLv3 or later) (since 2018-10-11) (hash sha1)
C++ conxstexpr template Math library with:
- multidimensional vectors and matrices
- geometry primitives with projection, distance and intersection functions
- coordinate systems conversions
- some routines

Depends on GCE-math C++ library as git submodule.

Used with clang (version 9 or 10) and gcc (version 9).
Written with C++17.
