    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。 vuHqOAFNs  
    (%tKGeb  
    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: $cc]pJy"}  
    enableservice('AutomationServer', true) Q~nc:eWD  
    enableservice('AutomationServer') 8xLvpgcZ  
    r.[9/'>  
    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 =^NR(:SaaU  
    g^=p)h3  
    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: >=wlS\:"  
    1. 在FRED脚本编辑界面找到参考. KATt9ox@  
    2. 找到Matlab Automation Server Type Library 23zB@aE_?1  
    3. 将名字改为MLAPP ^MuO;<<,.

    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。 k\A8Z[

    1. 创建Matlab服务器。 P/4]x@{ih  
    2. 移动探测面对于前一聚焦面的位置。 5Osx__6$t  
    3. 在探测面追迹光线 awGI|d  
    4. 在探测面计算照度 o@vo,JU  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2]hQ56Yv3  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 h>9GfF3  
    7. 用Matlab画出照度数据 $0 eyp]XC\  
    8. 在Matlab计算照度平均值 YuFJJAJ  
    9. 返回数据到FRED中 Ng2qu!F7
