Hi.
I am almost certain this is not problem with cygwin or the cygwin X server
running in your windows computer. I have used Matlab startup options
'matlab' (start Matlab with new GUI window and show Matlab logo)
'matlab -nosplash' (start Matlab with new GUI window, don't show logo)
'matlab -nojvm' (start Matlab command interpreter in the current terminal
without the GUI, show splash screen)
'matlab -nosplash -nojvm' (no GUI, no splash)
The page you referred to also mentioned 'matlab -nodesktop',
I think it might be same as -nojvm? I have a feeling that the desktop
is built using Java (because the 'no GUI' option is named 'nojvm').
Based on the above, one reason you don't see Matlab GUI window might be
that there is some problem with the installation of the JVM on the unix
server.
Another explanation might be that the cygwin X server or a firewall is
blocking the X windows, but this cannot be the case if you see the splash
screen.
Third option might be problem with the Matlab licenses, i.e. the Matlab
installed
in the unix server allows only limited number of simultaneous instances
running.
I experienced this about 10 years ago, when we had something like 2 or 5
licences on a server. Maybe the most likely problem is that the new Matlab
licence server is so advanced that it actually knows whether you are in a
remote
terminal or not, and it must be configured properly to allow remote X
windows.
I remember having these issues with Matlab6 when I started with my current
job.
At some point they bought new licence policy for the university or then they
just reconfigured the Matlab license server, don't remember which
one it was but after that I got graphics windows (I don't use the GUI).
You have to ask the details about this one from your unix server
administrator
(ask about the Matlab licenses, whether licence server is used,
does it allow remote windows, etc.).
