39INPUT:
40UvIn: structure stored as 'Userdata' on the uvmat interface
41IndexObjIn: object index for an existing objects stored in UvData
42ObjectData: structure containing the input object properties
43PlotHandles: structure containing the handles of the plotting parameter buttons on the uvmat interface (obtained by get_plot_handles.m)
