Stop the optimiser manually and get the final values

Dear all,
I am trying to optimize a function with many parameters using fminunc. The optimizer has been running for more than two days and i got message "number of function evaluations has been exceeded". I am honestly not an expert in optimization but I suspect that the optimizer is stuck in a paramter space or maybe the tolerance is too extreme and i need to looseen it a bit. I was just wondering whether I can stop the optimizer manually using "Control + C" and get the values of the parameters (even though they are not the optimal ones). Thank you very much for any help you could give me.
Kind Regards
S

No, when you control-C you are going to lose the values.
Consider using optimset() to add an OutputFcn that plots the values.
