    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 j9x<Y]  
    3LJ+v5T~  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ?cBwPetp  
    enableservice('AutomationServer', true) hYT0l$Ng  
    enableservice('AutomationServer') fo*2:?K&  
    G7` ko1-  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 _(W+S`7Z

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Bw)/DM]  
    1. 在FRED脚本编辑界面找到参考. E:sf{B'&  
    2. 找到Matlab Automation Server Type Library N ,'GN[s  
    3. 将名字改为MLAPP g|DF[

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 $k@O`xD,q

    1. 创建Matlab服务器。 ~rE|%o  
    2. 移动探测面对于前一聚焦面的位置。 l[mWf  
    3. 在探测面追迹光线 M)J5;^["  
    4. 在探测面计算照度 DbBcQ%  
    5. 使用PutWorkspaceData发送照度数据到Matlab &Cq`Y !y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8\@m - E!{  
    7. 用Matlab画出照度数据  &=@IzmA
