Question

I am trying to plot animation with matlab by the following code

height = 0.5;
for temp=1:1000
  clf('reset');
  height = 0.5-temp/1000;
   annotation(gcf,'rectangle',[0.957845238095236-0.1 0.1595238095238094 0.00941666666666667 height],'FaceColor',[1 0 0]);
   x = rand(1, 20);
   y = rand(1, 20);
   plot(x, y, '.', 'markersize', 5);
   axis([0 1 0 1]);
   drawnow;
end

If I hide the annotation code, it runs pretty good, but if the annotation was there, it flashes pretty bad and slow down the simulation pretty bad.

Answer 1

you can comment out the clf('reset'); line to solve this issue…
