Making a movie in octave

Short: Save each figure to a file using "print(filename)", and stitch together the movie with "ffmpeg" from the command line.

system("rm -rf plot-output; mkdir plot-output");

figure('visible','off');

x=0:0.01:5;

for n=0:100;

plot(x,sin(2*x-n/10));

axis("equal");

print(sprintf("plot-output/%05d.png",n));

endfor;

system("ffmpeg -sameq -i plot-output/%05d.png -y plot-output/movie.avi");

system("open plot-output/movie.avi");
