Plot animation with Struct. Variables

I was trying to turn this sequence for a single plot into a movie. Beam.x and Beam.y is a 100 spot vector. My original code is:

   plot(x,y,'--r','LineWidth',3);                      % This is the original position of the Beam 
  hold on                                             % Holds only the axes values                                         
  line(Beam.x,Beam.y,'color','b','linewidth',2);      % The New position of Beam
  xlabel('Beam Length (in.)','Color','g');
  ylabel(bstr,'Color','g');
  ylim([-(Beam.y(10)) max(Beam.y)]);
  legend('Without Deflection','With Deflection');
  title(astr,'Color','y','fontweight','b');
  set(S.ax,'YDir','reverse');
  set(S.ax,'XGrid','on');
  set(S.ax,'YGrid','on');  
  hold off

Anytime I try to turn it into a movie or anything of the sort I get the error:

The following error occurred converting from struct to double:
Error using double
Conversion to double from struct is not possible.

OR:

Error using capturescreen
Figure destroyed during getframe

Error in getframe (line 103)
     x=builtin('capturescreen', varargin{:});

Any ideas?

Which line of code shows the problem about converting struct to double? How are you trying to turn it into a movie?

   % Data 
  clear; close all;
  M = zeros(1,100);
  x = linspace(1,100);
  y = linspace(50,100);
  % figre
  figure(1);
  set(gcf,'Renderer','OpenGL');
  h = plot(x(1),y(1),'-r','linewidth',6);
  set(h,'EraseMode','normal');
  % Animation 
  j = 1;
  for j = 1:100
      set(h,'XData',x(j))
      set(h,'YData',y(j))
      plot(h)
      M(j) = getframe;
  end

movie(M,2)

The Code above is what I have been messing with to figure the animation thing and it keeps on returning the first error.

I have figured out how to make it work.

Can you please share? I am having the same problem. How did you get it to work?
