    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。 9d!mGnl  
    0(o.[% Ye  
    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: ff00s+  
    enableservice('AutomationServer', true) #IU^(W  
    enableservice('AutomationServer') 4AKPS&k;  
    a`LkP%  
    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 mo&9=TaG  
    p+b$jKWQ  
    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: 7&w|  
    1. 在FRED脚本编辑界面找到参考. #WAX&<m  
    2. 找到Matlab Automation Server Type Library g~76c.u-  
    3. 将名字改为MLAPP z8xBq%97us  
    ! w;/J^

    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。 A>_,tt

    现在将脚本代码公布如下,此脚本执行如下几个步骤: eL{$=Um  
    1. 创建Matlab服务器。 aS~~*UHW  
    2. 移动探测面对于前一聚焦面的位置。 dAy\IfZX=  
    3. 在探测面追迹光线 L<6nM ;d  
    4. 在探测面计算照度 Z_[L5B]Gwd  
    5. 使用PutWorkspaceData发送照度数据到Matlab js% n]$N  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 J5Ti@(G5V  
    7. 用Matlab画出照度数据 l \|sHn/  
    8. 在Matlab计算照度平均值 dEW= V"W  
    9. 返回数据到FRED中 M0`1o p1
