# EPS_GHIEP

A generalized Hermitian-indefinite eigenvalue problem.

## Notes

The problem is formulated as \(Ax=\lambda Bx\), where both \(A\) and \(B\) are real symmetric or complex Hermitian, but \(B\) is indefinite.

The solver will try to exploit the symmetry by using an indefinite inner product, which may turn the computation numerically unstable. To avoid this, solve the problem as non-Hermitian.
