Simple doubt: animating a plot

[Lucio Agostinho Rocha]

Hi,

I need to dynamically to plot some points in a discrete matrix using SciLab, something like this:

i=1;
while i>0;

   plot(y,x,'.w');
   plot(y,x+1,'.r');
   plot(y,x+1,'.w');
   plot(y,x,'.r');

   disp(i);
   i=i+1;

end;

But, in less of 100 iterations, the plotting is reducing your speed. What am I doing wrong? Some suggestion? I imagine that I need to flush something.

Thanks in advance,

Lucio
