Add a progress bar to nonlinear solver

Hi, All

I am using matlab nonlinear solver 'fminunc' to solve one pretty big nonlinear program. The whole solving progress takes about 1 min. I want to display one progress bar/waitbar during the process without taking too much resources from calculation. Something similar to the optimoptions/Display/iter but with a gui bar. Is there any good way to do this? Thanks in advance

You can use an options structure that invokes a plotfcn; see http://www.mathworks.com/help/optim/ug/fminunc.html#inputarg_options

Thanks, Mr. Walter! Again! I am still struggling with one proper customzied plot function but this points the direction. Thanks.

At the init stage you would create the waitbar. As the iterations progress you would update the waitbar. At the final stage you would remove it.
