EigsOptions

Base class: Object

Configuration options stored by iterative eigensolvers.

Members

NameDescription
is_hermitianGets whether the operator is treated as Hermitian.
is_realGets whether the operator is treated as real-valued.
krylov_dimensionGets the Krylov subspace dimension.
max_iterationsGets the maximum number of iterations.
modeGets the operator-function implementation mode. mode is an integer flag that can be used to select between the Spectra decomposition (serial; mode = 1) and Kothar decomposition (parallel; mode = 0) implementation. The Kothar decomposition is the default for Hermitian operators and disallowed for non-Hermitian operators.
num_eigenpairsGets the number of requested eigenpairs.
spectrumGets the target spectrum.
toleranceGets the solver tolerance.
