Detailed Description

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

A Belos::StatusTest debugging class for storing the absolute residual norms generated during a solve.

This implementation of the Belos::StatusTest base class stores the absolute residual norm provided by the iteration throughout an entire solve.

Note
This debugging status test will only work for single-rhs, single block solves.
