I am doing a lot of batch processing in which I creating many figures. I would like to keep these figures in the background while running the Matlab code without the Figure window popping up each time a new figure is created. Is there an easy way to do this? When the figure pops up it disrupts anything else you are doing on the computer.

I suggest you try export_fig
http://www.mathworks.com/matlabcentral/fileexchange/23629-exportfig
which can save a figure.
I have not experimented with it or looked at how it works, so I do not know if it would trigger a pop-up.

@Michael: AFAICS the problem concerns Linux only. Therefore I asked which OS you are using.
Does PRINT move the figure to the front also?

Please see this discussion
Someone indicated, though, that they could not get the figures to be saved when they used this technique. Possibly Oliver's export_fig would work. Or running MATLAB without a display and using one of the print() options that are documented as not needing a display.

getframe() also pops the relevant figure to the front in this version.

@Walter: Thanks, now I'm starting to understand the problem. Under Windows new figures are created on top of all other Matlab figures, but below the program which has the focus. And GETFRAME replies the contents of the screen at the figure (or axes) coordinates - if the figure is not topmost this is most likely not the wanted picture.

I won't promise you that this is the best solution, however, is one of them.
You could set the 'visible' property off the figure object to 'off'. It can be done something like this,
h1 = figure();
set(h1, 'Visible', 'off');
plot(x,y)
and when you want it to be shown,
set(h1, 'Visible', 'off');
or
figure(h1)
should also work.

This does work on stopping the figure from popping up. Now I have another issue since I am using getframe(gcf) to save the image to a file and the getframe command still pops up an image window.

figure_handle = figure(1)
figure_handle.WindowState = 'minimized'
.....
set(0, 'CurrentFigure', figure_handle)
plot([1:10],[1:10])
it worked for me

As long as I do not use Java or Windows-API methods to set the topmost flag of the window, I do not get this behaviour.
pause(10);
figure;
% Enable the Explorer, NotePad, any other program
% After the 10 secs have passed, ...
% the figure is created - in the background!
Which OS are you using? Do you create figures with WindowStyle='modal'?

@Michael: I did not even try to show a solution. I still do not see the problem at all, because the figures are *not* created in the forground at all - are they? I simply cannot confirm this: "When the figure pops up it disrupts anything else you are doing on the computer".
Of course GETFRAME does not work with figures not shown in the foreground, but you do not mention any problems with bad output here, but that the figure pops to the foreground. But PRINT handles background, out of visible screen area and Visible=off figures also.
Can somebody enlighten me, please?

getframe does work with figures that are not shown in the foreground and causes them to pop up into the foreground even if the figure visible is set to off as follows
h1 = figure();set(gcf,'Visible', 'off');

I think you can do this. It will pop up only once. The point is to re-use the figure. You can delete all its contents once they are printed. You can step through it to see the effect.
h=figure;
set(h,'visible','off');
plot(1:10);
print(h);%use your own command, this sends it to the printer
delete(get(h,'children'));
subplot(2,1,1); %do this just for illustration
plot(1:10);
subplot(2,1,2);
plot(1:10);
set(h,'visible','on');
delete(get(h,'children'));

Or even better, use clf(h) instead of delete(). Thanks to Walter's comment.

The delete() code shown here would not get hidden handles. Some figure children are created with hidden handles.

I am still having the problem with getframe still cuasing a pop up window. However I have found a viable solution using the function export_fig instead provided by Oliver Woodford.

Thanks to everyone for helping. This is the first time I used this resource.

I have this sort of problem too. I use Matlab on Mac OS. Suppose I have a program that draws in two figure windows which are overlapping. When I execute
figure(1); plot(some_data_vector); figure(2); plot(another_data_vector);
this puts figure 1 in front, draws on it, then puts figure 2 in front and draws on it. Is there any way I can update figure 2 without it becoming the front window?
I also run Matlab on a linux machine, and use XQuartz as the X-terminal. In that situation calling figure(1) puts that figure window in front of everything on the screen, which is more annoying still. Again, is there a way to draw in a figure (and have the graphics on the screen update) without the figure window being in front?

I specifically said above, "Yes: do not figure() it."
No calls to figure() inside your loop.
fig1 = figure(1);
ax1 = axes('Parent', fig1);
count=10;
Matrix1 = magic(100);
for i=1:count
mesh(ax1, Matrix1);
pause(1);
end

ok. Sorry, missed that.
How would it work with a subplot ?
( fig1 = subplot(2,1,1);figure(1); )

Got it :
count=5;
Matrix1 = magic(100);
Vector1=rand(10,1);
figure(4);
ax1= subplot(2,1,1);
ax2= subplot(2,1,2);
AX=[ax1,ax2];
for i=1:count
mesh(AX(1), Matrix1);
plot(AX(2), Vector1);
pause(0.5);
end

I feel like this didn't use to be the default behavior for me but now it is (figures popping up over other windows applications).
could it be a setting?
I'm at R2018b
