Problem with animated a 'surf' plot

I have a 3D-data structure which is effectively a series of 2D matrices which are used to built a 3d-surface plot. I'm trying to stitch them together into an animation, but all that seems to be grabbed is white space...

The code I'm using is below and I would be so grateful to anyone who could tell me what I'm doing wrong.

Zlim = max(max(max(Psi)));
NFrames = Nz;
%Window = gca;

Frames = moviein(NFrames);
%colormap('jet')
%map=jet;

for i = 1:NFrames
    surf(Psi(:,:,i));
    h= get(gcf,'CurrentAxes');
    zlim([0 Zlim]);
    Frames(i) = getframe(h);
    %Frames(i) = getframe;
end
%clf
movie2avi(Frames,'Output.avi','compression','Cinepak','fps',3);
%close(Window);

Well, I don't have your data. But I tried and it did show the animation. Maybe check your data Psi?

I used this and then run your code. The output.avi is correct too.

Psi=rand(100,100,10);
Nz=10;

Many thanks! I'm fairly certain the data's ok, as I see the graphs being plotted as the script runs (the data is generated by some C++ code). So I've tried to simplify:

Zlim = max(max(max(Psi))); Fig = newplot; FigHandle = get(Fig,'Parent'); Frames = moviein(Nz,FigHandle);

colormap('jet')

for i = 1:Nz surf(Psi(:,:,i)); zlim([0 Zlim]); Frames(:,i) = getframe(FigHandle); end

movie2avi(Frames,'OutputXY.avi','compression','Cinepak','fps',5);

When I run this, the surf plots are made, but the movie grabs only some empty, 2D axes.

Again, I don't have your data. Did you try my example using the random data? Did it show correctly and did you check whether Output.avi plays outside of MATLAB?
