Detailed Description

template<class ScalarType, class MV, class OP>
class Belos::GmresPolyOp< ScalarType, MV, OP >

Belos's class for applying the GMRES polynomial operator that is used by the hybrid-GMRES linear solver.

This operator is used as the interface to the matrix polynomial (phi(A)), solution (X), and right-hand side (B) of the linear system phi(A)X = B. Furthermore, it is also the interface to left/right preconditioning of the linear system.
