    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。 -kO=pYP*O  
     f!<mI8H  
    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: 8wOr`ho B  
    enableservice('AutomationServer', true) `?:'_K i  
    enableservice('AutomationServer') BLRrHaX0  
    U w)1yzX  
    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 4dO>L"

    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: "F^EfpcJ{9  
    1. 在FRED脚本编辑界面找到参考. O3Uu{'=0  
    2. 找到Matlab Automation Server Type Library ;iEqa"gO  
    3. 将名字改为MLAPP F]&9Lp} "

    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。 &8N\ 6K=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: uBM1;9h  
    1. 创建Matlab服务器。 N4Ym[l  
    2. 移动探测面对于前一聚焦面的位置。 -Bc.<pFqp  
    3. 在探测面追迹光线 NQb?&.C   
    4. 在探测面计算照度 9X-DR  
    5. 使用PutWorkspaceData发送照度数据到Matlab _T1e##Sq,  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?FLjvmE9  
    7. 用Matlab画出照度数据 Sdn] f4  
    8. 在Matlab计算照度平均值 ~DSle 3  
    9. 返回数据到FRED中 ji1A>jepF
