你是不是从客户那儿收到了几个xxx.pdm的文件，后缀mdl文件怎么打开，不要萌，这是 PowerDesigner 文件，里面就是你要看到的数据库表结构。
赶快去下载 PowerDesigner （如果你还没有的话）
下载好，安装！打开pdm文件，File > Open > 选择文件
.mdl文件 宏模块(Macros)文件 也可能是动画文件 你可以用第三方的软件来打开 如动画文件呢可以用3D Exploration
ctrl+shift+x，粘贴下面代码，Run
1、有一个已经编写好的mdl文件需要被模型调用。2、在Simulink中新建一个New Model，将“Simulink Library Browser”中的“Model”元件拖入新建的界面中。3、双击Model，进行参数设置。其中，“Model name”中要填入“Test.mdl。

1、在MATLAB的Command Window里输入： bdclose all; set_param(0,'CharacterEncoding', 'Shift_JIS');（注：Shift_JIS也可以换成windows-1252或ISO-8859-1）。2. 从Current Directory窗口打开需要打开的的那个.mdl文件。
如果你想讲所有图标导出到同一张sheet，其实我不建议，如果有需要，那么粘贴下面的代码：

1、第一步，打开matlab软件，依次单击“新建”-->“脚本”选项，见下图，转到下面的步骤。2、第二步，完成上述步骤后，输入以下代码，见下图，转到下面的步骤。3、第三步，完成上述步骤后，单击另存为name.m文件，见下图。
