As I see you are looking to plot the progress of the solver execution. Here's a reference example to achieve this:
openExample('optim/UseAPlotFunctionExample')
To plot the progress, the "PlotFcn" parameter in "optimoptions" must be set with function handles. For a given solver, you can either use a predefined set of functions or define a custom plot function.
For more information, refer to the "Plot Functions" documentation at the link below:
