    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。 H(*=9  
    \Im \*A   
    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: dBD4ogo1  
    enableservice('AutomationServer', true) v#YS`];B  
    enableservice('AutomationServer') :Jsz"vCg&s  
    f4\p1MYQ  
    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 T\$^>@  
    si"mM>e  
    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: =[tls^  
    1. 在FRED脚本编辑界面找到参考. xZ{|D  
    2. 找到Matlab Automation Server Type Library .of:#~  
    3. 将名字改为MLAPP 5M.n'*   
    I!i#=  
    JEkIbf?=r  
    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。 ]mLTF',5

    2. 移动探测面对于前一聚焦面的位置。 Y_ ;i  
    3. 在探测面追迹光线 ^zluO   
    4. 在探测面计算照度 Q!A3hr$IF  
    5. 使用PutWorkspaceData发送照度数据到Matlab p(b1I+!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !6 fpMo  
    7. 用Matlab画出照度数据 : 1f5;]%N  
    8. 在Matlab计算照度平均值 HBf8!\0|/  
    9. 返回数据到FRED中 "GC]E8&>H
