eigen@3

brew install eigen@3 v3.4.1 MPL-2.0 AND Apache-2.0 AND BSD-3-Clause AND Minpack AND LGPL-2.1-only keg-only

C++ header-only template library for linear algebra (matrices, vectors, solvers, and algorithms).

Why you might care

Eigen is the de facto standard for numerical computing in C++, used as a build dependency across scientific and robotics projects. It's keg-only because this is version 3; install it if your project specifically requires Eigen 3.4.x alongside other Eigen versions. Zero runtime overhead due to compile-time template optimization.
