Hello,

Say I have a Rosenbrock function (n=2) and I want to see each iteration when I use fminsearch(ros,x0)

How can I do that?

Thanks

The quickest way to see a plot of this is to type bandem at the command
prompt, then click simplex. Or, to have more control, you could specify
a plot function ('PlotFcns' with optimset).

Thanks a lot. Your recommendations helped me a lot. I've done it.
