Detailed Description
Provides a convergence criterion which looks at the reduction of the two-norm of the residual for the linear solvers.
For the ResidReductionCriterion, the error of the solution is defined as
![\[ e^k = \frac{\left| A x_k - b \right|}{\left| A x_0 - b \right|}\;, \]](form_17.png)
