Member Function Documentation

◆ set_matrix_mode()

void SLEPcWrappers::TransformationBase::set_matrix_mode ( const STMatMode  mode)
inherited

Set a flag to indicate how the transformed matrices are being stored in the spectral transformations.

The possible values are given by the enumerator STMatMode in the SLEPc library https://slepc.upv.es/documentation/current/docs/manualpages/ST/STMatMode.html

Definition at line 48 of file slepc_spectral_transformation.cc.

◆ set_solver()

void SLEPcWrappers::TransformationBase::set_solver ( const PETScWrappers::SolverBase solver)
inherited

Set solver to be used when solving a system of linear algebraic equations inside the eigensolver.
