    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。 &P%3'c}G  
    bGvALz'  
    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: 0)V<)"i  
    enableservice('AutomationServer', true) b:Lp`8Du  
        enableservice('AutomationServer') [e )j,Q1  
    5uK:f\y)l  
    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 e`#c[lbAAM

    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: |\ j'Z0  
    1. 在FRED脚本编辑界面找到参考. SLL%XF~/Sb  
    2. 找到Matlab Automation Server Type Library H'E >QT  
        3. 将名字改为MLAPP CUT D]:\  
         a[:0<Ek  
         Bl-nS{9"  
    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。 adh=Kp e!w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u{'bd;.7  
    1. 创建Matlab服务器。 s#ijpc>h  
    2. 移动探测面对于前一聚焦面的位置。 q28i9$Yqj\  
    3. 在探测面追迹光线 " z\T$/  
    4. 在探测面计算照度 N %-Cp)  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2*-s3 >VK  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 /i$ mIj`  
    7. 用Matlab画出照度数据 ] 5lp.#EB  
    8. 在Matlab计算照度平均值 Y&aFAjj  
    9. 返回数据到FRED中 lvIKL!;H
