    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。 ;=.QT  
    * QF3l0&  
    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: *L9s7RR  
    enableservice('AutomationServer', true) icf[.  
    enableservice('AutomationServer') ReCmv/AE  
    Hop$w  
    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 &!{wbm@

    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: !$>d75zli  
    1. 在FRED脚本编辑界面找到参考. nJ|8#U7  
    2. 找到Matlab Automation Server Type Library 2b]'KiX  
    3. 将名字改为MLAPP $e|G#mMd-

    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。 gq6C6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pQxaT$  
    1. 创建Matlab服务器。 byv(:xk|'e  
    2. 移动探测面对于前一聚焦面的位置。 7"r7F#D=G  
    3. 在探测面追迹光线 dyjzF`H  
    4. 在探测面计算照度 Tv0|e'^  
    5. 使用PutWorkspaceData发送照度数据到Matlab daaEN(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 -0Q:0wU  
    7. 用Matlab画出照度数据 ~$f+]7  
    8. 在Matlab计算照度平均值 '!!w|k d  
    9. 返回数据到FRED中 TD-d5P^Kek
