    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。 w%3Fg~Up  
    S<eZd./p6  
    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: @7@e`b?  
    enableservice('AutomationServer', true) 'Aj(i/CM  
        enableservice('AutomationServer') R:w %2Y  
    -G],H)M  
    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 K85_>C%g  
    b/sOfQ  
    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: xH<'GB)  
    1. 在FRED脚本编辑界面找到参考. wJ+U[a  
    2. 找到Matlab Automation Server Type Library vpm ]9>1[  
        3. 将名字改为MLAPP aKv[  
         ^\M dl  
         '7xxCj/*  
    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。 %K h2E2Pe

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /Hv* K&}M  
    1. 创建Matlab服务器。 J3;Tm~KJ_  
    2. 移动探测面对于前一聚焦面的位置。 g1ZV&X=2  
    3. 在探测面追迹光线 ^|wT_k\  
    4. 在探测面计算照度 f}[H `OF  
    5. 使用PutWorkspaceData发送照度数据到Matlab \ Y*h  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 `n 3FT=  
    7. 用Matlab画出照度数据 2)wAFO6u  
    8. 在Matlab计算照度平均值 Gn]d;5P=  
    9. 返回数据到FRED中 LthGZ|>
