11/30   how do program a matrix? (use a sparse matrix) ie: i want to track
        \_ See ucb.class.cs61a, thread "What is the Matrix?"
        and keep track of a person as to where they are in solving something
        (like following an specified path)- where they are at in a path, the
        path can have many entry points to the main road (or trunk of a tree).
        any ideas? thanks

        \_ Well, this is such an unclear question, I can't even begin to answer
           it (I could guess what you mean, but why?).  Try asking the question
           using more words in a newsgroup.
        \_ Unfortunately, no one can be told what the matrix is, they
           must see it for themself...
