ArnoldiSolveStatus Enumeration

Result of eigenvalue problem solve attempt using implicitly restarted Arnoldi iteration.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4
public enum ArnoldiSolveStatus
Member nameValueDescription
NormalExit0 Arnoldi iteration converged.
MaxIterationsExceeded1 Maximum iterations exceeded. All possible eigenvalues have been found.
NoShiftsDuringRestart3 No shifts could be applied during a cycle of the Implicitly restarted Arnoldi iteration. One possibility is to increase the size of NumLanczosVectors relative to NumEigenvectors.
InvalidParameters-1 Internal error. Examine the Info property of solution object ArnoldiEigenvalueSolution for the ARPACK returned error code.
ArnoldiFactorizationError-9,999 Error executing the implictly restarted Arnoldi iteration algorithm. See the value of the Info property of the ArnoldiEigenvalueSolution for further information.
