Detailed Description

template<typename ScalarT>
class Teko::PreconditionerLinearOp< ScalarT >

Class that wraps a PreconditionerBase object it makes it behave like a linear operator.

Class that wraps a PreconditionerBase object it makes it behave like a linear operator. Note that this is useful because it stores the neccessary state information for reconstructing a preconditioner.
