Our great sponsors
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.
xtensor
- Does anyone know any good open source project to optimize?
-
Which is the best way to work with matrices and linear algebra using c++?
I use xtensor: https://github.com/xtensor-stack/xtensor
-
Can you give an example of well-designed C++ code, and explain why you think it is so?
Currently, one of my current favorites is xtensor.

Eigen: A C++ template library for linear algebra
I wonder how Eigen compares to xtensor, which was inspired by Numpy and has support for views, slicing, and broadcasting?
-
When researching and developing new algorithms to be used in the real-world production environment, what is your workflow and how do you usually do it? Do I have to prototype in Python, and then rewrite all code in C++/Rust?
You can try eigen (http://eigen.tuxfamily.org/), armadillo (http://arma.sourceforge.net/) which is based on LAPACK which is what numpy is based on and xtensor (https://github.com/QuantStack/xtensor) which I think is the closest thing to numpy you’re gonna find in c++

Eigen: A C++ template library for linear algebra
Slightly tooting my own horn here; In case anyone is interested in a (trivial) comparison between them I have a tiny example project implemented both with Eigen and Arma (And Fortran and Python/numpy and Julia, FWIW): https://gitlab.com/jabl/tb
