    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。 Z+Kv+GmqH  
    $8jaapNm@  
    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: a`DWpc~  
    enableservice('AutomationServer', true) P;j&kuW|zL  
        enableservice('AutomationServer') u@AI&[Z  
    N2ni3M5v  
    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 -<8B,

    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: /rqqC(1  
    1. 在FRED脚本编辑界面找到参考. 3.(.*>  
    2. 找到Matlab Automation Server Type Library x:p}w[WM  
        3. 将名字改为MLAPP 5i|s>pD4z1

         $"/UK3|d  
    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。 _~juv&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: YdK _.t0Mu  
    1. 创建Matlab服务器。 +-U@0&Y3M  
    2. 移动探测面对于前一聚焦面的位置。 w- r_H!-  
    3. 在探测面追迹光线 |Mt&p#y  
    4. 在探测面计算照度 l(gJLjTH%  
    5. 使用PutWorkspaceData发送照度数据到Matlab HC?0Lj  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 YbzM6u2  
    7. 用Matlab画出照度数据 ]Qd{ '}+  
    8. 在Matlab计算照度平均值 %Nl`~Kz9U  
    9. 返回数据到FRED中 Jth=.9mrM
