M(i)=getframe(gcf) in for loop - Wrong result

Hi everyone. When I run the following code:

f=0.1;
hold on
for k=[0:0.1:1/f]
  plotv([real(exp(i*2*pi*f*k)); imag(exp(i*2*pi*f*k))],'-')
  x=floor(k*10+1);
  M(x)=getframe(gcf);
end
movie(M,1,12);

in the movie there is only a part of circle. Why? I'd like to view complete circle as well as it happens with the only plotv statement.

Thank you very much.

f=0.1;
hold on
k=0:0.1:1/f ;
for i = 1:length(k)
  plotv([real(exp(1i*2*pi*f*k(i))); imag(exp(1i*2*pi*f*k(i)))],'-')
  M(i)=getframe(gcf);
end
movie(M,1,12);
