Hi Volker,
All the programs were installed by the university, and I cannot install a
program myself as I am not the administrator. I asked the computer facility
help center, but they have not figured out a solution.
My Sage can do simple evaluations, but it cannot write to a location to
plot the graph:
sage: cd matplotlib-1.1.0/
[Errno 2] No such file or directory: 'matplotlib-RealNumber(1.1).gen(0)/'
/Network/Servers/smb-files.math.uwaterloo.ca/cifs.homedir/MacProfile/.sage
And the output of "mount" just gave a name error..
