    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。 AG|:mQO  
    \eXuNv_  
    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: ~&D5RfK5f  
    enableservice('AutomationServer', true) P:UR:y([  
        enableservice('AutomationServer') L0*f(H  
    v)~!HCG  
    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 7*r!-$  
    cRWYS[O?-  
    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: \CBL[X5tr  
    1. 在FRED脚本编辑界面找到参考. %<1_\N7  
    2. 找到Matlab Automation Server Type Library VDlP,Mm*  
        3. 将名字改为MLAPP UYGO|lkEU  
         2tS,q_-=  
         oGL2uQXX  
    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。 9O\yIL

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K/$5SN1  
    1. 创建Matlab服务器。 lt%9Zgr[u  
    2. 移动探测面对于前一聚焦面的位置。 _Nf%x1m5s  
    3. 在探测面追迹光线 !Y*O0_  
    4. 在探测面计算照度 Sc:)H2k`$  
    5. 使用PutWorkspaceData发送照度数据到Matlab mcWN.  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 P}vk5o'  
    7. 用Matlab画出照度数据 M&KJZ  
    8. 在Matlab计算照度平均值 W(EN01d\  
    9. 返回数据到FRED中 ZeH=]G4Zv7
