    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。 qa 6=W  
    *D=K{bUe'  
    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: :b<-[8d&  
    enableservice('AutomationServer', true) <CNE>@-f  
    enableservice('AutomationServer') ,_.@l+BM.  
    oF%^QT"R  
    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 H_% d3 RI  
    ee&nU(pK  
    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: ur/Oc24i1n  
    1. 在FRED脚本编辑界面找到参考. 6-*~ t8  
    2. 找到Matlab Automation Server Type Library 0M#N=%31  
    3. 将名字改为MLAPP 5 1o@b

    VFilF<jvu  
    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。 uIYcmF\?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <KHv|)ak  
    1. 创建Matlab服务器。 Ff[H>Lp~  
    2. 移动探测面对于前一聚焦面的位置。 /;(<fh<bY  
    3. 在探测面追迹光线 ]~?S~l%  
    4. 在探测面计算照度 x9xzm5  
    5. 使用PutWorkspaceData发送照度数据到Matlab $!3gN%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8_"3Yb`f  
    7. 用Matlab画出照度数据 hf_R\C(c  
    8. 在Matlab计算照度平均值 R&NpdW N  
    9. 返回数据到FRED中 r@|R-Binz
