    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。 "Y.tht H  
    2|y"!JqE1  
    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: I|!OY`ko  
    enableservice('AutomationServer', true) XX!%RE`M8  
        enableservice('AutomationServer') G Vr1`l  
    \7eUw,~Q>  
    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 /<k/7TF`  
    N% B>M7-=  
    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: Es`Px_k  
    1. 在FRED脚本编辑界面找到参考. F<1fX7c  
    2. 找到Matlab Automation Server Type Library nAato\mM  
        3. 将名字改为MLAPP G>=*yqo  
         ?<,l3pwqa  
         **0~K";\  
    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。 Wi<m{.%\E

    1. 创建Matlab服务器。 a!SiX  
    2. 移动探测面对于前一聚焦面的位置。 <=&`ZH   
    3. 在探测面追迹光线 dQX6(J j  
    4. 在探测面计算照度 klYX7?  
    5. 使用PutWorkspaceData发送照度数据到Matlab J{<X 7uB  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 S+6.ZZ9c  
    7. 用Matlab画出照度数据 nW:C/{n2tG  
    8. 在Matlab计算照度平均值 fbvL7* (  
    9. 返回数据到FRED中 W i.& e
