Animation

To create animation, first plot each frame and save the data in a corresponding column of a movie matrix, say, M.

>> axis equal  
>> M = moviein(16);      % allocate/initialize the matrix to have 16 frames         
>> set(gca,'NextPlot','replacechildren')  
>> for j=1:16       
     plot(fft(eye(j+16)))       
     M(:,j) = getframe;  
end

Once M is defined for all 16 frames, its time to run the animation.

>> movie(M,30)       % run 30 times
