    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。 2@!Ou$W  
    4q%hn3\  
    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: 2AN6(k4o  
    enableservice('AutomationServer', true) kFCjko  
        enableservice('AutomationServer') @log=^  
    $~ 6Y\O  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Um4$. BKD  
    BEU^,r3z  
    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: Y<1]{4Wt  
    1. 在FRED脚本编辑界面找到参考. c:;m BS>~  
    2. 找到Matlab Automation Server Type Library c{7<z9U  
        3. 将名字改为MLAPP SU. 9;I !

         OXT'$]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。 m5Q?g8

    2. 移动探测面对于前一聚焦面的位置。 'VH%cz*  
    3. 在探测面追迹光线 /K+GM8rtE  
    4. 在探测面计算照度 q ERdQ~M,  
    5. 使用PutWorkspaceData发送照度数据到Matlab s> d /9 b  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 +Ndo$|XCy]  
    7. 用Matlab画出照度数据 !%v=9muay  
    8. 在Matlab计算照度平均值 CqF= 5z:A  
    9. 返回数据到FRED中 W_]Su
