One way is to run a similar code as shown below in Live Editor. It will automatically create a video from the for loop that you can export.
matrix = rand(10,3);
matrix2 = rand(10,3);
ii=1;
foot1 = scatter3(matrix(ii,1),matrix(ii,2),matrix(ii,3),'filled','r');
hold on
foot2 = scatter3(matrix2(ii,1),matrix2(ii,2),matrix2(ii,3),'filled','g');
xlim([0 1])
ylim([0 1])
zlim([0 1])
for ii = 2:size(matrix,1)
foot1.XData = matrix(ii,1);
foot1.YData = matrix(ii,2);
foot1.ZData = matrix(ii,3);
foot2.XData = matrix2(ii,1);
foot2.YData = matrix2(ii,2);
foot2.ZData = matrix2(ii,3);
drawnow
end
v = VideoWriter('NameYourVideo.avi');
v.FrameRate = 1;
open(v);
for ii = 2:size(matrix,1)
foot1.XData = matrix(ii,1);
foot1.YData = matrix(ii,2);
foot1.ZData = matrix(ii,3);
foot2.XData = matrix2(ii,1);
foot2.YData = matrix2(ii,2);
foot2.ZData = matrix2(ii,3);
drawnow
frame = getframe(gca); %Note if you use gca (get current axis), make sure it doesn't change size - x, y, and z limits were defined above in this example to prevent this.
writeVideo(v,frame);
end
close(v)
