    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。 v\!Cq+lFML  
    9,Dw;|A]  
    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: 1 +M !EW  
    enableservice('AutomationServer', true) g_tEUaiK  
    enableservice('AutomationServer') g0/ R\  
    Gk58VODo  
    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 ^Vh^Z)gGi

    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: +dq2}gM  
    1. 在FRED脚本编辑界面找到参考. Y@ ;/Sf$Q  
    2. 找到Matlab Automation Server Type Library HH(2  
    3. 将名字改为MLAPP zKYN5|17  
    ,T  3M  
     d*([!!i  
    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。 n3/ Bs

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c(3idO*R)  
    1. 创建Matlab服务器。 <Z~Nz>'r  
    2. 移动探测面对于前一聚焦面的位置。 yQu/({D  
    3. 在探测面追迹光线 UNrO$aX!1'  
    4. 在探测面计算照度 vPy."/[u  
    5. 使用PutWorkspaceData发送照度数据到Matlab Opy{i#>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;uZq_^?:9&  
    7. 用Matlab画出照度数据 6_9@s*=d>  
    8. 在Matlab计算照度平均值 2ss*&BR.  
    9. 返回数据到FRED中 gK *=T
