Question

Matlab figure and multiple processes

Asked by: zzhang2006


Is it possible to have a backgound program running within Matlab from the command window, like in UNIX/Linux?

What I would acomplish in particular is that I want a dot in a figure, say, figure 1, be flashing
by turning it on/off with the set(ch(1),'Visible','on/off') in a while loop. But I don't want it to hold the command window "busy" and I can not anything else from the command window.

Experts, if it is not possible to have multiple processes acessing a figure (or object it you will) in Matlab. Are there any other packages or solutions to this kind of problems?

Thanks in advance

Ze 

ch = get(gca,'Children')
 
ch =
 
  695.0002
  694.0001
  693.0001
  688.0001
  687.0001
  686.0001
  .....
% making it blinking
while(true)
set(ch(1),'Visible','on')
pause(0.3)
set(ch(1),'Visible','off')
pause(0.3)
end

Hi,

I think what you are after is called Threading. MATLAB doesnt specifically have threading but you can simulate it as http://forum.allaboutcircuits.com/showthread.php?t=8815 describes. They suggest that you use a timers exprired event to fire your action (in your case turning the visibility on and off). That way the processor isnt tied up in a pause.

Hope this helps
