PEPLINEAR#

PEPLINEAR = “linear” - A linearization-based solver that uses EPS to solve the resulting linear eigenproblem.

Notes#

A linear eigenvalue problem is obtained by linearization, as described in section Linearization, where the linearization parameters can be set via PEPLinearSetLinearization(). Note that the linearization is done differently depending on PEPProblemType. Then the matrices of the linearization are passed to an EPS object. Use PEPLinearGetEPS() to configure this solver.

By default, the matrices of the linearization are handled implicitly via shell matrices, but this can be changed with PEPLinearSetExplicitMatrix().
