class | SolverBase |
Base class for spectral transformation classes using the SLEPc solvers which are selected based on flags passed to the spectral transformation.
SLEPcWrappers::TransformationXXX
, where XXX
is your favourite transformation type, can then be implemented in application codes in the following way for XXX=INVERT
with the solver object eigensolver
:
and later calling the solve()
function as usual:

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

void SLEPcWrappers::TransformationBase::set_solver | ( | const PETScWrappers::SolverBase & | solver | ) |
Set solver to be used when solving a system of linear algebraic equations inside the eigensolver.
