    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。 ]!-R<[b 6  
    U,d2DAvt  
    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: :SdIU36  
    enableservice('AutomationServer', true) o[imNy~~  
    enableservice('AutomationServer') ^T+<!k  
    _-(z@  
    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 (E IRz>

    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: H! #5!m&  
    1. 在FRED脚本编辑界面找到参考. k|fh\F+$  
    2. 找到Matlab Automation Server Type Library eA10xpM0  
    3. 将名字改为MLAPP (w}r7`n  
    |<'10  
    %qONJP  
    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。 v(a9#bMZU

    现在将脚本代码公布如下,此脚本执行如下几个步骤: & 8zk3  
    1. 创建Matlab服务器。 1X Q87~  
    2. 移动探测面对于前一聚焦面的位置。 FV`3,NFk  
    3. 在探测面追迹光线 /Ql6]8.P  
    4. 在探测面计算照度 zkH<aLRB  
    5. 使用PutWorkspaceData发送照度数据到Matlab Lax9 "xI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w"yK\OE  
    7. 用Matlab画出照度数据 < JGYr 4V  
    8. 在Matlab计算照度平均值 fQ^h{n  
    9. 返回数据到FRED中 K@I+]5E%?
