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
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
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:
