Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Which is the best way to work with matrices and linear algebra using c++?
You can have a look at https://github.com/kokkos/stdBLAS (it's an implementation of the proposed linear algebra extensions for future C++).

C++23: Near The Finish Line
It has the same BSD license as Kokkos: https://github.com/kokkos/stdBLAS/blob/main/LICENSE

Linear Algebra Library Reccomendations?
The BLAS and LAPACK have C interfaces, and they generally don't allocate memory unless you ask them. (Some BLAS implementations allocate internal storage for rearranging matrix data.) There are a few C++ BLAS wrappers; here is one of them.
-
Is there an OOP-wrapper library for cublas?
The second one is stdBLAS by kokkos. It doesn't even use cuBLAS but it's a reference implementation of P1673. This paper describe what could be a blas API in the std. I would recommend trying to do something equivalent on your side.

Vector math library benchmarks (C++)
I actually used that library rather than GLM back in college (specifically this fork) and thought about including it, but it doesn't look like it's been maintained in a long time and seemingly has poor cross platform support (incl for different processor architectures).

Which is the best way to work with matrices and linear algebra using c++?
there's also VectorMath but it's SIMD so I don't know how it bodes with robot architectures

pinocchio - A fast and flexible implementation of Rigid Body Dynamics algorithms and their analytical derivatives
kokkos - Kokkos C++ Performance Portability Programming Ecosystem: The Programming Model - Parallel Execution and Memory Abstraction
xtensor - C++ tensors with broadcasting and lazy computing
plf_hive - plf::hive is a fork of plf::colony to match the current C++ standards proposal.
