    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。 4;anoqiG\  
    D<}z7W-  
    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: S9~X#tpKe  
    enableservice('AutomationServer', true) C^ngdba\  
    enableservice('AutomationServer') +_Nr a  
    %:I\M)t}k  
    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 '<N^u@tF7  
    ? b;_T,S[  
    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: =O= 0 D  
    1. 在FRED脚本编辑界面找到参考. 'n`+R~Kkh  
    2. 找到Matlab Automation Server Type Library mQ 1)d5  
    3. 将名字改为MLAPP r* #ApM"L

    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。 $OI 6^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h LYy  
    1. 创建Matlab服务器。 W[trsFP1?  
    2. 移动探测面对于前一聚焦面的位置。 v{%x,K56  
    3. 在探测面追迹光线 s Xyc _3N  
    4. 在探测面计算照度 6H+'ezM  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9Q{-4yF9k  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 npsDy&  
    7. 用Matlab画出照度数据 on?<3eED  
    8. 在Matlab计算照度平均值 5,/rh,?  
    9. 返回数据到FRED中 `Y Hn L4
