Silent plot

It may be usefull start calculation in background. MATLAB figure auto focusing may be a problem. To solve this problem set figure invisible

set(0, 'DefaultFigureVisible', 'off');

After background calculation you may return setting by command

set(0, 'DefaultFigureVisible', 'on');

Also you may use

figHandles = findobj('Type','figure');

to find handles for all figure and next use

set(figHandles, 'Visible', 'on');
