To display only the "uiprogressdlg" and hide the parent "uifigure", we can follow the below method:
fig = uifigure(...);
d = uiprogressdlg(fig, ...);
fig.Visible = 'off'; % Hide the underlying figure
drawnow; % Ensure UI updates
close(d);
fig.Visible = 'on'; % Show it again if needed
This quickly removes the figure window, leaving the progress dialog visible.
