This solved the hold issue, thanks!

I have, however, found another plot issue and I have difficulty to see what is causing problem. I have  a
script that uses the toolbox:

    http://www.signal.uu.se/Toolbox/dream/

(which I'm the main developer for) that generates the error:

when I try to do:

figure(1);
clf;
mesh(x,z,cm);

The script seems to set the octave-gnuplot intraction in a state so that
nothing can be plotted:

The only thing that resets plotting is to do a: clear all (clear functions is  not enough).
I have no idea what it is that causes this problem (I can post the script but then the toolbox must
be installed to run it).

PS. The script runs fine using matlab or in octave given that I do something like:

save cm.mat cm x z Ro Ro_orig
clear all
load cm

figure(1);
clf;
mesh(x,z,cm);
