DESCRIPTION

Monitors  the  behaviour  of the iterates x managed by Iterative­
Solver. The convergence test is relative and is based on the dif­
ference    of    two    succeeding   iterates   i.e.,   `$arallel
x^{k}-x^{k-1}                                             arallel
/arallel
x^{k-1}                                                   arallel
.
