intercepting residues as array

[Dominik Szczerba]

Would it be easy to intercept the rnorms as computed in e.g. fgmres into 
an array? E.g. have

   0 KSP Residual norm 5.955965225039e-04
   1 KSP Residual norm 8.064336982160e-05
   2 KSP Residual norm 2.550695121313e-05
   3 KSP Residual norm 7.872959324551e-06
   4 KSP Residual norm 2.084257872716e-06

as {5.955965225039e-04, 8.064336982160e-05, ...} for independent logging 
etc.

I know how I can do it the long way (e.g. writing my own convergence 
test where I have an access to rnorm), but I was wondering if there was 
a short way.

with regards,
Dominik
