How do I use Euler - Matlab like numerical program.

I’ve compiled Euler but I can’t seem to get the graphics part of it to work.

euler_1_42.tgz is found in /usr/free/qnx4/photon/utils/

In the file description this program is said to use photon but I can’t run
it from photon. I can run it in a terminal window but when it’s supposed to
show the graphical data it does nothing.

Any help would be greatly appreciated.
