class slepc4py.SLEPc.PEP.ProblemType

  Bases: `object`

  PEP problem type.

  - `GENERAL`: No structure.

  - `HERMITIAN`: Hermitian structure.

  - `HYPERBOLIC`: QEP with Hermitian matrices, \(M>0\), \((x^TCx)^2 > 4(x^TMx)(x^TKx)\).

  - `GYROSCOPIC`: QEP with \(M\), \(K\) Hermitian, \(M>0\), \(C\) skew-Hermitian.
