    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。 c-Gp|.C  
    MBLZ:A| C  
    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: k %I83,+  
    enableservice('AutomationServer', true) bWPsfUn#  
    enableservice('AutomationServer') N:j 7J  
    y:G%p3h)[  
    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 {QG.> lB  
    F>;Wbk&[|  
    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: V"Q\7,_k.  
    1. 在FRED脚本编辑界面找到参考. -FeXG#{)  
    2. 找到Matlab Automation Server Type Library A#U! KX  
    3. 将名字改为MLAPP XM'tIE+|  
    A U~DbU0O  
    i'Y8-})  
    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。 Q_mphW:[

    现在将脚本代码公布如下,此脚本执行如下几个步骤: E@}F^0c  
    1. 创建Matlab服务器。 6?Ncgj &@  
    2. 移动探测面对于前一聚焦面的位置。 7FX4|]  
    3. 在探测面追迹光线 IZVP-  
    4. 在探测面计算照度 !Tzo &G  
    5. 使用PutWorkspaceData发送照度数据到Matlab g*k)ws  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &raqrY|V  
    7. 用Matlab画出照度数据 tE*BZXBlm  
    8. 在Matlab计算照度平均值 ax@H^Gj@2  
    9. 返回数据到FRED中 X[Y0r
