Controlling the frame rate in a MATLAB video

HI, I am creating a avi video with matlab, the problem is that the video is too fast, how can i do slower?

    aviobj = avifile('example');
    fig=figure(20);
    for i=1:14
    for k=1:8
        im(:,:,:)=a(i,:,:,:);
        imshow(im);
        axis off
        F = getframe(fig);
        aviobj = addframe(aviobj,F);
    end
    end
    close(fig);
    aviobj = close(aviobj);

thank you very much

Use the frame rate option.
