【 在 goodman 的大作中提到: 】
: 用print -dpng filename.png或export_fig输出，都有一个附件所示的锯齿。但是如果手工放大再输出就没有这个锯齿，请问怎么可以去掉输出多边形产生的这个锯齿？后期批量处理也可以，非常感谢！[upload=1][/upload]

两条线相交造成的吧
看一下画图的选项中，有没有关于线的端点相关的选项

我对 matlab 不熟悉，在R中，相关的选项有：

     ‘lend’ The line end style.  This can be specified as an integer or
          string:

          ‘0’ and ‘"round"’ mean rounded line caps [_default_];

          ‘1’ and ‘"butt"’ mean butt line caps;

          ‘2’ and ‘"square"’ mean square line caps.

     ‘ljoin’ The line join style.  This can be specified as an integer
          or string:

          ‘0’ and ‘"round"’ mean rounded line joins [_default_];

          ‘1’ and ‘"mitre"’ mean mitred line joins;

          ‘2’ and ‘"bevel"’ mean bevelled line joins.

     ‘lmitre’ The line mitre limit.  This controls when mitred line
          joins are automatically converted into bevelled line joins.
          The value must be larger than 1 and the default is 10.  Not
          all devices will honour this setting.
