    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。 cdzzS?$)  
    +*)B;)P  
    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: .b  N0!  
    enableservice('AutomationServer', true) 1xM&"p:  
    enableservice('AutomationServer') $L:g7?)k  
    wc~a}0uz  
    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 X"iy.@7  
    xE;fM\7pu  
    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: 79:x>i=  
    1. 在FRED脚本编辑界面找到参考. :7:Nx`D8  
    2. 找到Matlab Automation Server Type Library $3Wl~ G}  
    3. 将名字改为MLAPP w|?Nq?KA  
    U G^6I5  
    6n%^ U2H/-  
    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。 ~O@V;y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <T  
    1. 创建Matlab服务器。 L\y,7@1%AT  
    2. 移动探测面对于前一聚焦面的位置。 3iH!;`i  
    3. 在探测面追迹光线 ,D ;`t  
    4. 在探测面计算照度 s( Kf%ZoE  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?$-OdABXHK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _QY0j%W  
    7. 用Matlab画出照度数据 qhF/iUE  
    8. 在Matlab计算照度平均值 :Nc~rOC _  
    9. 返回数据到FRED中 u"pn'H
