If you have access to an X terminal, or a PC equipped
with X server software, you can access Matlab remotely on `
unixs.cis.pitt.edu`. See the Math 0250 web page http://calculus.math.pitt.edu/0250
for instructions on getting X server software for your PC or Mac and running
Matlab remotely.

If you have access to a Linux system, you can install Gnu Octave and use it instead of Matlab. Check the Math 0250 web page http://calculus.math.pitt.edu/0250 for a link to the Octave web pages.
