Detailed Description

relative convergence monitor for residual vectors.

NAME: CMRelResidual - relative convergence monitor for residual vectors

DESCRIPTION:

Monitors the behaviour of a residual vector imported from an "IterativeSolver" via a "LinEqCommBlk" object, i.e. no internal storage. The convergence test is relative, `$S(\cdot

allel \! v^{k} \!\parallel/\parallel \! v^{0} \!\parallel)`: `\leq \varepsilon$`, where `$v^{k}$` equals one of the `$`k`$`th residuals `$r^{k}$`, `$s^{k}$` or `$z^{k}$` and `$`S`$` is a scaling obtained from spectral properties (if this information is available).
