    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。 O]t\B *%}  
    a>U6Ag<  
    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: @cZ\*,T  
    enableservice('AutomationServer', true) VKy5=2&  
        enableservice('AutomationServer') ZI,j?i6\  
    /?Vdqci  
    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 eI^gV'UK  
    &M[MEO`t8  
    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: ?KCivf  
    1. 在FRED脚本编辑界面找到参考. )u0O_R  
    2. 找到Matlab Automation Server Type Library 69Nw/$  
        3. 将名字改为MLAPP O16r!6=-n  
         $ADPV,*gG  
         Jn=42Q:>  
    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。 :/6()_>bO

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lkb2?2\+  
    1. 创建Matlab服务器。 Z ] '>  
    2. 移动探测面对于前一聚焦面的位置。 .Rvf/-e  
    3. 在探测面追迹光线 34z+INkX  
    4. 在探测面计算照度 4@6 <  
    5. 使用PutWorkspaceData发送照度数据到Matlab ><=rIhG%H@  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 /Pk:4,  
    7. 用Matlab画出照度数据 TiyUr [  
    8. 在Matlab计算照度平均值 G=|70pxU  
    9. 返回数据到FRED中 eRs&iK2y
