    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。 1bg@[YN!;  
    Rr4CcM  
    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: 15 o.j!S  
    enableservice('AutomationServer', true) xm|4\H&Bg  
    enableservice('AutomationServer') m5w9l"U]H  
    )8 :RiG2B  
    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 =t$mbI   
    4Qel;  
    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: :ECK $Cu  
    1. 在FRED脚本编辑界面找到参考. Y-q@~v Z]  
    2. 找到Matlab Automation Server Type Library BhW]Oq&  
    3. 将名字改为MLAPP x}<G!*3

    P}9Y8$Y>U  
    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。 Cw[Od"B\?U

    现在将脚本代码公布如下,此脚本执行如下几个步骤: s.;KVy,=Bu  
    1. 创建Matlab服务器。 ~hz@9E]O  
    2. 移动探测面对于前一聚焦面的位置。 d50IAa^p6J  
    3. 在探测面追迹光线 2${,%8"0s  
    4. 在探测面计算照度 5V nr"d  
    5. 使用PutWorkspaceData发送照度数据到Matlab "1!.^<V*  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .;Utkf'I  
    7. 用Matlab画出照度数据 o\ow{ gh9  
    8. 在Matlab计算照度平均值 $qtU  
    9. 返回数据到FRED中 _RaVnMJKX4
