I need to set a time limit or a max number of iterations on the premade function, fzero.m. Can anyone please help me with this?
Thanks, Eric

Use optimset() to create a parameters structure that sets an output function. The output function should check the iterations or the time elapsed and return true if the optimization should terminate.

Thanks for your help. I've been looking into this, but I can't figure out how to pass the starting time into the output function. Would I put t0=clock; at the top of fzero.m?
