    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。 JvO1tA]ij  
    V#Wy` ce  
    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: ]o'o v  
    enableservice('AutomationServer', true) 9VW/Af  
        enableservice('AutomationServer') =F@ +~)_  
    :|bL2T@>[  
    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 s*PKr6X+  
    `PARZ|  
    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: p)SW(pS  
    1. 在FRED脚本编辑界面找到参考. I~6) Gk&  
    2. 找到Matlab Automation Server Type Library 2^B_iyF;  
        3. 将名字改为MLAPP  }#m9Q[  
         RL}?.'!  
         wa@Rlzij>  
    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。 #&.Znk:@.f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Y#@D% a8  
    1. 创建Matlab服务器。 FGn"j@m0  
    2. 移动探测面对于前一聚焦面的位置。  Gsh9D  
    3. 在探测面追迹光线 oL]uY5eZoe  
    4. 在探测面计算照度 :of([e|u6  
    5. 使用PutWorkspaceData发送照度数据到Matlab <{W{ Y\_A>  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 myj/93p}`b  
    7. 用Matlab画出照度数据 y7+@ v'  
    8. 在Matlab计算照度平均值 jj`#;Y  
    9. 返回数据到FRED中 #]dm/WzY
