arpack-ng

This package provides Rust bindings for arpack-ng, a library solve large eigenvalue problems.

Currently only the functionality of zneupd is exposed. This means that this library can be used to calculate eigenvalues and vectors using Implicitely Restarted Arnoldi Method.

Supported are ndarray matrices (or alternative dynamically sized nalgebra matrices with the nalgebra flag) or closures that calculate a matrix vector multiplication.

Refer to the simple example for the matrix case and the closure example otherwise.
