Redraw Circle in mwsamp Control

This example shows how to call a method of the mwsamp control to redraw a circle.

Create the control. MATLAB® opens a figure window and displays a circle and text label.

myfigure = actxcontrol('mwsamp.mwsampctrl.2',[0 0 200 200]);

Display the properties of the control.

            Label: 'Label'
           Radius: 20
    Ret_IDispatch: [1x1 Interface.mwsamp2_ActiveX_Control_module._DMwsamp2]

You can change the text displayed in the Label property and the radius of the circle.

Display the methods for the mwsamp control. MATLAB displays the list alphabetically; methods with initial uppercase names are listed before methods with lowercase names.
