    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。 Ek [V A\G  
    :qV}v2  
    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: iY=M67V  
    enableservice('AutomationServer', true) O1@-)<_71  
    enableservice('AutomationServer') $J/Z~ (=JT  
    wff&ci28  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 &CvNNDgrJ  
    00') Ol&  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Lp; {&=PIo  
    1. 在FRED脚本编辑界面找到参考. _E e`Uk  
    2. 找到Matlab Automation Server Type Library &^ sgR$m  
    3. 将名字改为MLAPP uzO%+B!

    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。 ZQT14.$L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8&6h()  
    1. 创建Matlab服务器。 \*}JdEHB  
    2. 移动探测面对于前一聚焦面的位置。 v;S7i>\  
    3. 在探测面追迹光线 kL.JrbM"  
    4. 在探测面计算照度 ]Dm'J%P0}  
    5. 使用PutWorkspaceData发送照度数据到Matlab p @@TOS  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Q 'R@'W9  
    7. 用Matlab画出照度数据 s(Of EzsH=  
    8. 在Matlab计算照度平均值 aU]A#g
