The 32-bit version of Matlab seems to run fine on athena.dialup:
echo export MATLAB_ARCH=glnx86 > ~/.matlab7rc.sh
echo export MATLAB_JAVA=/mit/java/current/distrib/i386_ubuntu1004/jre >> ~/.matlab7rc.sh
cat /mit/matlab/current/distrib/bin/.matlab7rc.sh >> ~/.matlab7rc.sh
matlab
(MATLAB_ARCH can be set as an environment variable on the command line
instead of ~/.matlab7rc.sh. So could MATLAB_JAVA if you didn’t
unconditionally overwrite it in /mit/matlab/current/distrib/bin/matlab.)

Have you tried running the 32-bit version on a 64-bit machine?
maple -binary IBM_INTEL_LINUX
I can’t get it to run on either linerva or athena.dialup over X
forwarding, but in both cases it gets as far as spewing an X error to
/dev/null, which according to strace looks like
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 45 (X_OpenFont)
Serial number of failed request: 54
Current serial number in output stream: 55
So presumably it might work if I had the right fonts installed.
