options menu with nodisplay [Matlab]

Hi!
I'm trying to create an options menu in Matlab 7.4.0.287 (R2007a) and student version 7.8.0.347 (R2009a).

I'm running Matlab with "matlab -nojvm -nodisplay" and using the command "menu."

The documentation says that if there is no display, it will display a text-based menu. However, I'm getting the error below.

I'm a Matlab "G"UI newbie, so if I had to set up my "graphics" environment, I didn't know (or do) it.

Thanks!

>> menu('choice?', 'a', 'b')
??? Error using ==> set
Width and height must be > 0.

Error in ==> menu>local_GUImenu at 238
set( menuFig, 'Position', [winLeftGap bottom winWide winHigh] );

Error in ==> menu at 53
k = local_GUImenu( xHeader, ArgsIn );

Hi us,
In that reference, I don't see how to make a text-only options menu (with or without jvm, display, or desktop). The documentation still indicates that it should be possible. Could you please give another hint, or suggest a way to print a text only options menu?

Thanks!
-Jeff

OK! I've made a little progress. If I ssh to the Matlab box without enabling X11 forwarding, start Matlab (with our without nodisplay and nojvm), I get the following warning, and the text menu *works*!

Warning: Unable to open display , MATLAB is starting without a display.
You will not be able to display graphics on the screen.

However, with X11 forwarding enabled (ssh -X), then I cannot get the text menu to work (with or without nodisplay and nojvm).

So, do you know how I can run Matlab without a display in a way that works (without changing how I login to the shell)? Apparently, nodisplay isn't sufficient?

Thanks!
-Jeff
