    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。 <sE0426 {  
    B0T[[%~3M  
    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: VnAJOR7lrx  
    enableservice('AutomationServer', true) 80U07tJ  
    enableservice('AutomationServer') 3V>2N)3`A  
    +pURF&Pr  
    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 `9IS+Z  
    E`}KVi57  
    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: CXwDG_e  
    1. 在FRED脚本编辑界面找到参考. ,dOd3y'y  
    2. 找到Matlab Automation Server Type Library 9 N[k ?kUZ  
    3. 将名字改为MLAPP bsO78a~=P  
    =yJJq=!  
    e p* (  
    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。 D7T(B=S6

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  df;-E  
    1. 创建Matlab服务器。 tQ=M=BPZ  
    2. 移动探测面对于前一聚焦面的位置。 maW,YOyRN  
    3. 在探测面追迹光线 }@>=,A4Y  
    4. 在探测面计算照度 /"Ws3.p  
    5. 使用PutWorkspaceData发送照度数据到Matlab {B8W>>E  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 u|t<f`ze  
    7. 用Matlab画出照度数据 A6v<+`?  
    8. 在Matlab计算照度平均值 794V(;sW,  
    9. 返回数据到FRED中 tEhYQZ
