    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。 xAqb\|$^  
    N^#ZJoR  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: )T/0S$@  
    enableservice('AutomationServer', true) Z8# (kmBdB  
    enableservice('AutomationServer') 88VZR&v   
    aUzBV\Yd}  
    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 1 9&<|qTz

    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: J,V9k[88  
    1. 在FRED脚本编辑界面找到参考. 7R`M,u~f2^  
    2. 找到Matlab Automation Server Type Library *?Lv3}E  
    3. 将名字改为MLAPP 1/RsptN"v  
    Te.Y#lCT$  
    m`v2: S}  
    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。 ;'?l$ ._

    现在将脚本代码公布如下,此脚本执行如下几个步骤: J{l1nHQZSu  
    1. 创建Matlab服务器。 e>7]w,*|  
    2. 移动探测面对于前一聚焦面的位置。 Usr@uI#{J  
    3. 在探测面追迹光线 " W!M[qBW  
    4. 在探测面计算照度 B268e  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6FUw"|\u{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Ipf|")*  
    7. 用Matlab画出照度数据 G'rxXJq  
    8. 在Matlab计算照度平均值 9:fOYT$8  
    9. 返回数据到FRED中 d_AK `wR
