What's the possible reason for that?

Hi all,

I am writing an M-file to solve my non-linear equation system. Finally it works, but the problem is sometimes it takes about 20 seconds for a solution, sometimes the computer is just suspended. Even when I run the 1st time, it's ok, then rerun (same parameters), it gets stuck.
Can anyone tell me what probably the reasons for that?

Thank you.

Are you doing this on campus? It could be the licence, or many other people are using the program. Other than that, I can't think of too many reasons.
