Dear all,
recently I started reading a book (Finite Volume Methods for
Hyperbolic
Problems) which is utilizing its own set of functions in order to
undertake numerical calculations (CLAWPACK). These are to be
visualized
from within Matlab afterwards.
As a Linux user I hence tried executing the delivered Matlab-scripts
from within Octave and unfortunately ran into a problem. I am running
Octave 3.0.0 from Ubunty Hardy.

error: `colstyle' undefined near line 9 column 18
error: evaluating for command near line 8, column 1
error: called from `get_plotstyle' in file
`/home/schoeller/Work/Coding/CLAW/matlab/get_plotstyle.m'
error: near line 59 of file
`/home/schoeller/Work/Coding/CLAW/matlab/plotframe1.m'
error: evaluating while command near line 76, column 1
error: near line 93 of file
`/home/schoeller/Work/Coding/CLAW/matlab/plotclaw1.m'
get_plotstyle.m at line 8:
for i = 1:length(pstyle),
[l,c,m,msg] = colstyle(pstyle{i});
if (~isempty(msg))
plotframe1.m at line 59:
[linestyle,linecolors,markerstyle] = get_plotstyle(pstyle,maxlevels);
plotclaw1.m at line 93:
plotframe1 % routine claw/matlab/plotframe1.m
% does the plotting for this frame
end % main loop on frames
So I figured that the colstyle command was missing. Searching I found
colstyle.m is part of the Specgraph toolbox of Matlab, so I copied
http://www.nersc.no/~even/matlab/toolbox/specgraph/colstyle.m into the
respective directory and re-executed. I thus receive the error message

warning: get: invalid property `UserData'
error: value on right hand side of assignment is undefined
error: evaluating assignment expression near line 11, column 9
error: called from `get_slices' in file
`/home/schoeller/Work/Coding/CLAW/matlab/get_slices.m'
get_slices.m at line 11:
amrplot = get(gcf,'UserData');
When plotting something and requesting its properties via get(gcf)
I do
not see any property named UserData. Now I am wondering whether
this is
a general incompatibility problem or whether there would be a quick
fix.
On http://wiki.octave.org/wiki.pl?ObjectGraphics it looks as if
UserData
is a pending question from ObjectGraphics.
I would be greatful for any advice.
Best wishes
Sebastian
