    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。 !dqC6a  
    m}]{Y'i]R  
    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: V._-iw]v  
    enableservice('AutomationServer', true) D;,p?]mgO~  
        enableservice('AutomationServer') QQJGqM3a2  
    f1'ByV'2  
    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[egCC\Mo_

    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: /X}1%p  
    1. 在FRED脚本编辑界面找到参考. |_53So: g  
    2. 找到Matlab Automation Server Type Library mR0`wrt  
        3. 将名字改为MLAPP Kzev] er  
         ` m 5\  
         ,EQ0""G!  
    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。 rZI63S

    现在将脚本代码公布如下,此脚本执行如下几个步骤: xU;SRB   
    1. 创建Matlab服务器。 M6-uTmN:d  
    2. 移动探测面对于前一聚焦面的位置。 B>u`%Ry&  
    3. 在探测面追迹光线 `^#Rwn#  
    4. 在探测面计算照度 XfcYcN  
    5. 使用PutWorkspaceData发送照度数据到Matlab -Mo4`bN  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 DgEdV4@p  
    7. 用Matlab画出照度数据 \>$zxC_  
    8. 在Matlab计算照度平均值 TQ\#Z~CbK{  
    9. 返回数据到FRED中 T"\d,ug5[
