Dear all,

Hi, I want to maximize a multi-variable function myfun(x), where x is a vector over which we maximize. I'm using Global Optimization Toolbox and it takes a very long time to run. What I want is, when I stop running the Global Optimization Toolbox command, I want Matlab to give the best solution up to that point.

I think my question is, is it possible to write a function with many outputs, where the first output is what I want to maximize and the other outputs store what I want up to that point? If so, how would I write it?

I'd appreciate any and all help. Thank you!

Best, John

It is possible that a global output function would do what you want. But I am not completely sure what you are asking, so if this doesn't look like a good suggestion, then try asking again.
