print causes matlab to crash in linux

David Doria — Thu, 24 Apr 2008 14:00:19 -0400

x=1:10;
y=x.^2;
plot(x,y);
print(gcf,'-dpng','test.png');

this crashes matlab in linux!! works fine in windows.

anyone know why this may be??

Thanks,

Dave

After more looking, it seems that does in fact work - that
was just a simple demo i thought I could give. However:

peaks
saveas(gcf,'test.png','png')

doesn't crash matlab, but saves an entirely black image!

If I run saveas(gcf,'test3.png','png') on my actual data (a
surf plot) then matlab does crash.

Any clues?

I'm having a similar problem.

When I try to save an image file, using
saveas(<handle>,'filename.eps','epsc2'),
it crashes my entire desktop, not just matlab. It seems to happen
when i have a relatively complicated image, for example one with 4
subplots. It doesn't crash every single time, I can usually save a
file once, then the second time it crashes.

It does this in both command line mode and in desktop mode.

The only solution I've found is to use the "print" command, e.g.

print -f2 -depsc2 filename.eps
(where -f<...> is the figure handle, in my case, I'm trying to save
figure 2).

It doesn't seem to be crashing (yet).

There can be a number of causes. I suggest you contact your local support
office so they can address the specific situations.

That particular message only applies if MATLAB was started with the -nojvm option

I had a similar problem in which not only matlab crashed,
but the entire xsession. I posted my fix here:
