Module eigen 

Eigenvalue and eigenvector solvers for matrices and graphs.

Provides three levels of access:

• eigen_matrix_symmetric — eigenvalues of a real symmetric matrix given as a matrix-vector product closure. Uses Lanczos iteration.
• eigen_matrix — eigenvalues of a general (possibly non-symmetric) real matrix via Arnoldi iteration.
• eigen_adjacency — eigenvalues of a graph’s adjacency matrix (convenience wrapper).

All solvers are pure Rust with zero external dependencies.
