why fmincon returns different results every time

Hi fellows,

I am using fmincon to do the optimization problem. But every time I run it it gives me different result. Is there anyone who know what the reason could be?

Cheers

• Do you have a rand() in there that makes your function non-deterministic?
• Is your function non-deterministic in some other way?
• Are you using the same starting point, x0?
• Are you modifying the options at all?

The more details you can provide us with the better.
