EigenKrylovSolver

class dolfin.cpp.la.EigenKrylovSolver(*args)

Bases: dolfin.cpp.la.GenericLinearSolver

This class implements Krylov methods for linear systems of the form Ax = b. It is a wrapper for the Krylov solvers of Eigen.

Create Krylov solver for a particular method and names preconditioner
