    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。 W}#eQ|oCV  
    ^_ L'I%%[  
    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: |S[Gg  
    enableservice('AutomationServer', true) vggyQf%  
    enableservice('AutomationServer') zY_BnJ^  
    S]mXfB(mh  
    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 ~c~N _b  
    f#}P>,TP  
    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: ,<s'/8Ik  
    1. 在FRED脚本编辑界面找到参考. H4p N+  
    2. 找到Matlab Automation Server Type Library ~6L\9B )  
    3. 将名字改为MLAPP |1C=Ow*"  
    $ ,Y\  
    5D 9I;L{  
    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。 kaf4GME]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: k44s V.G4L  
    1. 创建Matlab服务器。 C1_':-4  
    2. 移动探测面对于前一聚焦面的位置。 [F{q.mZj  
    3. 在探测面追迹光线 ew -5VL   
    4. 在探测面计算照度 L]I ;{Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab D]n9+!Ec1f  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |2w,Np-  
    7. 用Matlab画出照度数据 ;zVtJG`  
    8. 在Matlab计算照度平均值 'oSs5lW  
    9. 返回数据到FRED中 ~/s(.oji
