# EPS_PGNHEP

A generalized non-Hermitian eigenvalue problem with positive (semi-)definite \(B\).

## Notes

The problem is formulated as \(Ax=\lambda Bx\), where \(A\) is non-symmetric (or non-Hermitian), but \(B\) is symmetric (or Hermitian) and positive (semi-)definite.

The problem will be solved with a non-Hermitian solver, but using an inner product induced by matrix \(B\).
