Lately, I've been using "fminsearch" to do some optimizations. I am
wondering how to break current iteration and restart a new one during
"fminsearch" is running. Specifically, I set a logic condition in the
function which is cited in "fminsearch", when this condition is met I
want to break the current iteration of "fminsearch" without return any
results and restart a new iteration. 

Does any one here have some ideas about which function would be
employed to achieve above procedure?

Thanks in advance!
