Follow-up Comment #2, patch #8569 (project octave):

I followed PCG and GMRES scripts in that the actual iterations start at 2, but
have forgotten to reduce the iteration count before ending. I am happy for
resvec to be a column-vector. (Note that the Octave BiCG script returns a
row-vector that is 8x1 with iter = 9 for this case - I was having some trouble
figuring out which scripts to follow, as there are considerable differences
between them.)

If matching MATLAB is the aim, then should the resvec array return the
residual norms instead of relative residual norms?
