How do I generate a video from images that I create on MATLAB?

I am generating a missile simulation input for which I created a sequence of images using an iterative for loop. The code starts with a single aerial image using which I have generated a sequence of images that make it seem like the image is rotating. I used campan, camzoom, camva and drawnow to consecutively display the sequence of images when I run the code. It looks like a video of an aerial image rotating when I run the code. My problem is, that I need to extract a video from these generated images, and save it on my computer to use as input for the missile simulator. Please help.

Sir, my apologies. Your demo seems to resemble what I'm looking for. I shall try it out and get back to you. Many thanks.

Sir, this is one portion of the code I have. Now, I need to generate a similar video with the resultant images. Please help? Thank you.
A = imread('aerial.jpg');
imshow(A, 'InitialMagnification', 'fit')
camtarget([3300 1500 0])
for i = 10:-0.1:9
for j = 4:8
camzoom(j)
camva(i)
campan(1, 0)
drawnow
% imsave
end
end

hi, i saw the FAQ in the link mentioned in yor answer, but i have a question about your code. is their any way to control timing of the video/transition time of images? e.g i want to use a small number of images 5-10 to make a 5-10 seconds animation, when i used your code, it gave me an animation for only 1 second, which was not what i wanted. thanks in adance for your help

There is a property of the video object created by VideoWriter that is FrameRate. Set it to the rate you want.
