I coded using movie2avi. There is no error message, however, I couldn't get a movie. The movie showed 'white screen' without any movie, which I wanted to make.

My code is

 a=data(:,5);%%data from Meeting\Wamit
b=a.*pi/180;%%make radian angle
p=zeros(10000,3);
p(:,1)=data(:,1);
p(:,2)=data(:,2);
p(:,3)=data(:,4).*exp(b*1j);
x=zeros(100,2);
y=zeros(100,2);
u=reshape(p(:,1),100,100);%%change matrix form to draw mesh graph.
v=reshape(p(:,2),100,100);
w=reshape(p(:,3),100,100);
%mesh(u,v,real(w));
%xlabel('x(ft)');
%ylabel('y(ft)');
%zlabel('surface elevation(ft)');
%title('surface elevation');
for t=1:200
   w1=w.*exp(1j*(2*pi/7.99)*(0.1*t));
     mesh(u,v,real(w1));
   pause(0.1);
   M(t)=getframe; 
end
movie2avi(M,'wamit6.avi','compression','none','FPS',40);

I could watch the iteration of graph, which I wanted to make. However, the movie, which was made by coding, showed 'white screen'. Running code didn't show any error message.

I don't know the reason why movie always showed 'White Screen' without any error message.
