How do I close a specific figure

I have a GUI. This GUI runs a simulation the at the end of it I open a figure to display results.

When I re-run the simulation - the old figure is kept open.

How do I close the old figure without closing the GUI?

('close all' close all the windows including the GUI).

close(gcf)

Answer 1

[João Miguel Marinheiro]

close(figure(<number of figure>))

Answer 2

[Morteza]

In the section of simulation use these line:

handles.H = figure(2)

plot(rand(10,1));

waitforbuttonpress;

close(handles.H)

when you press any button ploter figure automatically will be closed

Answer 3

[Sean de Wolski]

hFig = figure;
surf(peaks);

To close that figure:

close(hFig)

[Nimrodb]

I thought about that - but when I re-run the simulation - I see that hFig is "unassigned"

[Sean de Wolski]

Then that handle hasn't been stored. You should store that handle in whatever is calling the simulation so that it can close it.

[Nimrodb]

as a global in the beginning of the main function? The simulation is called from a GUI built by GUIDE.

The flow is:

GUI made by GUIDE --> Simulation ---> Results function (that opens a Figure)

Where and how do I save the figure handle?

I am passing here to let my contribution as I had exactly the same problem. If you know the name or tag of the GUI do:

          % Close all figures still openned except the GUI which property 'name' is equal 'nameOfQUI'
          figHandles = findobj('type', 'figure', '-not', 'name', 'nameOfGUI');
          close(figHandles);

or

          % Close all figures still openned except the GUI which property 'tag' is equal 'tagOfQUI'
          figHandles = findobj('type', 'figure', '-not', 'tag', 'tagOfGUI');
          close(figHandles);

@Laercio Barbosa

You only need to fill in ''tag'' and ''tagOfGUI'', right? So if the tag of my GUI is ''figure1'', then:

         figHandles = findobj('type', 'figure', '-not', 'figure1', 'figure1');
          close(figHandles);

should do it? It doesn't work for me and I am searching for my error...

[Laercio Barbosa]

@beginner94, sorry for the late response.

No. You don't need fill all the fields you mentioned. Only the last one. Basically what we are doing is:

Find objects of type figure, but not that one where figure property is equal figure1.

or still

Find objects of type figure, but not that one where tag property is equal "tagname".

In your case

figHandles = findobj('type', 'figure', '-not', 'figure', 'figure1');
close(figHandles);
