What is your goal? To display graphics on the screen even though the program
has been triggered by a CGI script (which in theory could be from anywhere,
perhaps even several simultaneously) ? Or to get rid of the warning? If you
want to get rid of the warning include -nodisplay in the matlab options (for
Unix.) If you want to display on to the screen, use -display followed by the
display name in the command-line options (for Unix), and set your X
authorization to accept connections from the web server (not generally a good
idea.)
