Eigenvalue solver parameters

Wherever a record syntax shows [eigensolverparams (…)], that stands for the following group of attributes, written directly in the same record.

Syntax

stype (in) [smtype (in)] solverParams (s)

Parameters

stype (in)

Eigenvalue solver type; see Table 6.

[smtype (in)]

Sparse matrix storage scheme. It must be compatible with the solver type; see Sparse linear solver parameters.

solverParams (s)

The parameters specific to the selected solver.

Table 6 Eigenvalue solver parameters.

Solver type	stype id	Solver parameters
Subspace Iteration	0 (default)	None.
Inverse Iteration	1	None.
SLEPc solver	2	Requires smtype 7. See also the SLEPc manual.
