    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。 'e&4#VLH^  
    ;(afz?T  
    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: N>~*Jp2;  
    enableservice('AutomationServer', true) NlDM/  
    enableservice('AutomationServer') 0L6L_;o  
    D(&OyZ~Q+  
    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 o ZAjta_4

    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: pZR^ HOq  
    1. 在FRED脚本编辑界面找到参考. d. a>(G  
    2. 找到Matlab Automation Server Type Library oqE -q\!H  
    3. 将名字改为MLAPP K'tz_:d|  
    QdRMp n}q  
    Re2kD/S3  
    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。 r1\.Jz

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %cv%u6 b  
    1. 创建Matlab服务器。 qEpBzQ&gX6  
    2. 移动探测面对于前一聚焦面的位置。 YlA=? X  
    3. 在探测面追迹光线 pQ>V]M  
    4. 在探测面计算照度 UX0tI0.tg  
    5. 使用PutWorkspaceData发送照度数据到Matlab xXbW6aI"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 QXrK-&fju  
    7. 用Matlab画出照度数据 wHCsEp(  
    8. 在Matlab计算照度平均值 YK-R|z6K  
    9. 返回数据到FRED中 'FVT"M~
