That looks like a shell prompt, not a Python prompt

nfold.py is a python script -- you can't just type in the name once 
inside python and have it work.  It would require something like

--> import os
--> os.chdir('path/to/nfold.py') # don't include nfold.py ;)
--> import nfold
--> import sys
--> sys.argv = ["--folds=5", "--data=spambase.data",
... "--spec=spambase.spec", "--rounds=500", "--tree=ADD_ALL",
... "--generate" ]
...
--> nfold.main()  # assuming it has a main function that can be called
                   # in this manner

and that probably won't work.  What you probably want to do is execute 
the command "python /path/to/nfold.py --fold=5 ..." (include the 
nfold.py this time ).  I have no idea how to do that from Matlab.

Good luck!
