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
