    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。 &+02Sn3A  
    6oQ7u90z*  
    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: bxPa|s?  
    enableservice('AutomationServer', true) 7;@YR  
        enableservice('AutomationServer') 0sSBwG  
    -*[)CR-{  
    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 >pZ _  
    QqF*SaO>  
    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: i@6g9\x+  
    1. 在FRED脚本编辑界面找到参考. 0LC]%x+"  
    2. 找到Matlab Automation Server Type Library "qC3%9e  
        3. 将名字改为MLAPP q1YNp`]0i8  
         :(OV{ u  
         Ff0V6j)ji  
    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。 X ]&`"Z]

    1. 创建Matlab服务器。 Na]Z%#~  
    2. 移动探测面对于前一聚焦面的位置。 (&)uWjq `  
    3. 在探测面追迹光线 K)l*$h&-  
    4. 在探测面计算照度 R~A))4<%%  
    5. 使用PutWorkspaceData发送照度数据到Matlab 'bZw-t!M@  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 LjGLi>kI~  
    7. 用Matlab画出照度数据 ZTqt4H  
    8. 在Matlab计算照度平均值 H/[(T%]o  
    9. 返回数据到FRED中 S.iUiS"
