    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。 C7 ]DJn  
    >[H&k8\7n  
    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: 8\)U|/A7  
    enableservice('AutomationServer', true) ]r6BLZ[%  
    enableservice('AutomationServer') Ur([L&  
    nJ*mEB  
    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 v=.z|QD^1  
    $TA6S+  
    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: e@:P2(WW l  
    1. 在FRED脚本编辑界面找到参考. :\+{;;a@  
    2. 找到Matlab Automation Server Type Library ~i }+P71  
    3. 将名字改为MLAPP }>;ht5/i/

    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。 juCG?}di;

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  t$H':l0  
    1. 创建Matlab服务器。 @Xve qUUU  
    2. 移动探测面对于前一聚焦面的位置。 j(%gMVu  
    3. 在探测面追迹光线 T1(j l)  
    4. 在探测面计算照度 HCJ8@nki  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5"kx}f2$  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ke}Y 2sB  
    7. 用Matlab画出照度数据 :J Gl>V  
    8. 在Matlab计算照度平均值 "B9[cDM&
