    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。 cI/Puh^3  
    *:tfz*FG$G  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: V|`w/P9g4  
    enableservice('AutomationServer', true) e]k\dj;,^%  
    enableservice('AutomationServer') >tQ$V<YB  
    kl[Jt)"4@  
    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 iQ#dWxw4

    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: 5kdh!qy[$,  
    1. 在FRED脚本编辑界面找到参考. <C{uodFll  
    2. 找到Matlab Automation Server Type Library \F5d p  
    3. 将名字改为MLAPP `Dp_c&9]

    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。 [Zj6v a

    现在将脚本代码公布如下,此脚本执行如下几个步骤: oF {u  
    1. 创建Matlab服务器。 s_RUb  
    2. 移动探测面对于前一聚焦面的位置。 \VAm4   
    3. 在探测面追迹光线 |:)ARH6l#  
    4. 在探测面计算照度 k+;XQEH  
    5. 使用PutWorkspaceData发送照度数据到Matlab *h4x`luJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ''3b[<  
    7. 用Matlab画出照度数据 d*tn&d~k,  
    8. 在Matlab计算照度平均值 /P koqA,  
    9. 返回数据到FRED中 Q8?:L<A
