    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。 <!(n5y_  
    2`U&,,-Mf  
    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: eSBf;lr=  
    enableservice('AutomationServer', true) h5keYBA  
        enableservice('AutomationServer') 6lAo`S\)eX  
    l>?vjy65  
    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 ]LOtwY  
    .T-p]9*p  
    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: HKw:fGt/o^  
    1. 在FRED脚本编辑界面找到参考. k $&A  
    2. 找到Matlab Automation Server Type Library "a{f? .X.  
        3. 将名字改为MLAPP v>!}cB/6

    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。 Bcon4

    3. 在探测面追迹光线 vJUB;hD  
    4. 在探测面计算照度 M?u)H&kEl  
    5. 使用PutWorkspaceData发送照度数据到Matlab hI{Yg$H1  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 L"/ato  
    7. 用Matlab画出照度数据  m:Abq`C  
    8. 在Matlab计算照度平均值 (Z +C  
    9. 返回数据到FRED中 iUBni&B
