iData: saveas: avi movie

[farhi]

Create a rotating movie for 2D+ objects.

fig=figure;
plot(s);
aviobj = avifile('example.avi')
for ang=0:5:360
  view([45 ang])
  aviobj = addframe(aviobj,getframe(fig));
end
close(fig)
aviobj = close(aviobj);

ok, but need:

• view([ ang 30])

this does not work with recent Matlab version which use:

• VideoWriter object https://fr.mathworks.com/help/matlab/ref/videowriter-object.html
