matlab导出动画gif

获取当前绘图窗口，一帧一帧的追加写入Gif图片即可

% Write to the GIF File 追加Gif图片
    frame = getframe(h); % 获得当前画图窗口h
    im = frame2im(frame); 
    [imind,cm] = rgb2ind(im,256); %图片颜色转换256
    filename = ['aa',num2str(1),'.gif'];%图片名称
    if loop == 1
        imwrite(imind,cm,filename,'gif', 'Loopcount',inf,'DelayTime',0.2);
        %有一些参数网上有说明 delaytime gif播放时间差
    else
        imwrite(imind,cm,filename,'gif','WriteMode','append','DelayTime',0.2); 
    end
