How can I keep figure boxes from popping up while running script.

I am very new to MATLAB and programming in general, so please bear with my syntax/poor code.
I am trying to make an animation for my project in an introductory MATLAB class. I want to show how different sorts "look" as they are being processed. I have the script doing what I want, but I can't get it to stop opening new figure windows for each loop pass. This results in hundreds of windows being opened.
Here is the bubble sort for example.
Ba=input('Array to be sorted: ')
n=length(Ba)
c=[1:length(Ba)]
counter1=1
for y=1:n-1
for x=1:n-1
if Ba(x+1)<Ba(x)
temp=Ba(x);
Ba(x)=Ba(x+1);
Ba(x+1)=temp;
counter1=counter1+1
figure('Visible','off');
bar(c,Ba);
saveas(gcf, sprintf('name%d', counter1), 'bmp');
end
end
end
It saves the images to be made into an animation later, but it is very slow as it opens hundreds of windows.

Are you wanting to save the plot created on each pass of your loop? If so, just move the figure creation line out of the loop. As long as you're not holding your figure, the data plotted on its axes will be overwritten on each pass and then saved, without opening a new figure.
As an example, compare:
for i = 1:10
y = rand(1,30);
figure
plot(y);
saveas(gcf, sprintf('myfig_%d', i), 'bmp');
end
to:
figure
for i = 1:10
y = rand(1,30);
plot(y);
saveas(gcf, sprintf('myfig_%d', i), 'bmp');
end
So, in short, the below line needs to be moved outside your loop:
figure('Visible','off');

Has anyone else had a problem with this line?...
figure('Visible','off');
I tried this to stop all of my figures from popping up as they were generated, and it worked. However, afterwards, when I wanted to look at them, I couldn't open the figures. Has anyone else had a similar issue? How did you solve it?

Instead of making a new figure window on each loop iteration, use clf to clear the current one and reuse it!
