Consider a section math/science/linear algebra utilities #345

Open bernhardmgruber opened 1 year ago

bernhardmgruber commented 1 year ago

There are a few mathematical utilities in C++ and a lot is upcoming.

We have the standard math functions (e.g. sin etc), and the special math functions (#344). There is std::complex (#343). We also don't mention the C++20 <numbers> header, which finally contains std::numbers::pi :)

C++23 has std::mdspan as MD array abstraction (e.g. for matrices and tensors). Built on this, we will get a standard interface for linear algebra (based on BLAS using std::mdspan) in C++26. std::mdarray and std::submdspan may also come in C++26.

This may deserve a small section of its own at some point.
