files = dir('*.mat') ;
N = length(files) ;
% create the video writer with 1 fps
writerObj = VideoWriter('myVideo.avi');
writerObj.FrameRate = 10;
% open the video writer
open(writerObj);
for i = 1:N
S = load(files(i).name) ;
A = S.A ; % let A be the data stored in .mat file
imshow(A)
drawnow
% write the frames to the video
F = getframe(gcf) ;
writeVideo(writerObj, F);
end
% close the writer object
close(writerObj);
fprintf('Sucessfully generated the video\n')
