[Animation]: To animate a figure as function of several variables

Hi, I have a function(my_figure) that creates a figure by taking an array of variables(q) as argument and plotting according to the values of those variables.

my_figure(q)

I wish to animate a collection of such figures by varying the array of variables in a loop. I have come across 'refresh data' but cannot figure out how that is supposed to help me. Please help.

See getframe and movie functions in the MATLAB documentation.There is a following example:

Z = peaks;
figure('Renderer','zbuffer');
surf(Z);
axis tight;
set(gca,'NextPlot','replaceChildren');
for j = 1:20
    surf(sin(2*pi*j/20)*Z,Z)
    F(j) = getframe;
end
movie(F,20) % Play the movie twenty times

Thanks for your reply. It helps. But I seem to be getting an error that:

Error using hgMovie

Movie contains uninitialized frames

Error in movie (line 41)

        builtin('hgMovie',varargin{:});

I can see that All the frames have been alloted a value. I cannot understand the reason for this error.

I have given a part of my code for reference.

figure;

a_plot_m(q_eq);

axis tight;

set(gca,'NextPlot','replaceChildren');

for j =1:10

      qm=q2(:,j);

  car_plot_m(q_eq)

  F(j) = getframe(gcf);

end

movie(F,10) % Play the movie
