MATLAB: Close command and Invalid figure handle

closefiguregui

I have a GUI in which I have a button create a plot: p(1)=plot(…).

I have a reset button that, upon being pressed, executes close(p).

When I hit the reset button, I get the error:

??? Error using ==> close at 94
Invalid figure handle.
Error in ==> Pulse>reset_Callback at 870
close(p)

However, while the GUI and p(1) plot figure are open, if I type close(p) in the Matlab Command Window, it closes the figure without any errors. Any idea what's causing this?

Or:

close(ancestor(p, 'figure'))

Why not just do close(h)?

If there's a possibility that h never gets created at all (no histograms), you can use exist to check before doing the close

if exist('h','var')
  close(h)
end

EDIT Rereading the question, perhaps the problem is that h(2) may exist as a variable, but not refer to a valid figure? In that case,

close(h(ishandle(h)))

MATLAB: Only close specific figures

Are you able to just keep a vector of the figure handles (for A and B separately) as you create them, such that you can close the ones you want? For example,

>> handleA(1) = figure;
>> handleA(2) = figure;
>> % etc

>> handleB(1) = figure;
>> handleB(2) = figure;
>> % etc

Then, to close only A figures, you can do

>> close(handleA)

I guess I'm having trouble understanding your use case.

Also, regarding closing all figures, is there a reason you don't just use

>> close all
