Okay, so we went through and got rid of that vague error, and now we get a new error. The command with(Matlab); returns a list of commands available, and so everything seems to be running okay, but when we try to open the link (via openlink(); or another command which would cause openlink(); to be run), we get this error: Error, (in OpenEngine) Maple/Matlab Link: Can't start Matlab engine After much searching on the net and through the Maple and Matlab scripts on our machine, we are dumbfounded as to what this error is trying to tell us. Any suggestions? Thank you.
I'm sorry, that was my mistake. I should have said: >restart; >a:=4; >anames(user); a >%; 4 ... And sometimes after asking a question here I feel such a fool. I know that I've tried methods similar to what you just wrote, but nothing worked until I typed in what you put. Wow, I'm dumb. ^_^

I could have sworn I tried the command >showstat(LinearAlgebra:-LA_Main:-Eigenvalues); and it didn't work. Well, trying it again netted me exactly what I needed. Thank you. And thank you for summing up what that large block of code does. ^_^
In my experience as a TA, I saw many of the same things you're talking about. I could tell exactly who worked with whom, and who copied wohm. The thing is, where I am now has a system set up to automatically grade Maple homeworks. The system does actually throw up a red flag if the student's name at the top of the worksheet is not correct, but that is easily circumvented. It's that ease of circumvention that motivates me to find more secretive ways of checking a homework's authenticity. I don't plan on telling students if I set a hidden checksum in their homeworks, but it's not something that I'm going to actively try to keep secret either. If it weren't for the automated grading, I would agree with you: Having a hidden checksum in homework that's already graded by hand is unnecessary.

It's not the clever students I'm worried about. Those are usually the students who can do or learn to do the homeworks effectively.

That's true, but we're at least trying to stop blatant cheaters. There's always going to be something that we can't prevent. There's always going to be some way to slip around the system.

... I don't know why I didn't see this before. Thank you. evalM is exactly what I needed.
