    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。 &'}RrW-s  
    [N#, K02mk  
    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: [ji#U s:h  
    enableservice('AutomationServer', true) or';A'k  
    enableservice('AutomationServer') sU@nc!&Y@  
    .QN>z-YA6:  
    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 ZGYr$C~  
    )Ccq4i  
    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: cxr=k%~}J  
    1. 在FRED脚本编辑界面找到参考. +E.GLn2 /  
    2. 找到Matlab Automation Server Type Library Q^e}?v%=%3  
    3. 将名字改为MLAPP tjluk

    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。 8=Z9T<K

    现在将脚本代码公布如下,此脚本执行如下几个步骤: viMzR(JU  
    1. 创建Matlab服务器。 I$0)Px%z  
    2. 移动探测面对于前一聚焦面的位置。 kAC&S!n  
    3. 在探测面追迹光线 5&q8g;XiEM  
    4. 在探测面计算照度 Ju :CMkv  
    5. 使用PutWorkspaceData发送照度数据到Matlab P:aJ#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 @qnD=mE  
    7. 用Matlab画出照度数据 86mp=6@  
    8. 在Matlab计算照度平均值 V*iH}Y?^p  
    9. 返回数据到FRED中 "G@g" gP
