Loading a fig file without opening

Hi,

I have .fig in the current directory and wish to extract data from it. I used the following code for this purpose,

open('power.fig');
a = get(gca,'Children');
xdata = get(a, 'XData');
ydata = get(a, 'YData');

The code works. My problem is it also opens the fig file in a separate figure window. I don't want that to happen. I just want to extract the data.

Ofcourse I could use,

close figure

But it just takes out the graph and shows an empty figure window.

I would be very much grateful if somebody could help me in this.

Thanks in advance!

f=openfig('power.fig','invisible')
a=get(f,'Children')
...
close(f)
clear f

The figure still pop up quickly before closing.

How can I prevent this?

Try this:

>> load test.fig -mat hgS_070000
>> hgS_070000

hgS_070000 = 

  struct with fields:

          type: 'figure'
        handle: 1
    properties: [1×1 struct]
      children: [1×1 struct]
       special: []

It should work, I just tested it on R2020b Update 7 and it does.

But beware that is undocumented (and probably unintended) behavior. So it might change suddenly.
