    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。 0\f3La  
    m\~{l=jIS  
    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: E"7 iU  
    enableservice('AutomationServer', true) z-*/jFE  
    enableservice('AutomationServer') HE0UcP1U  
    zj.;O#hW  
    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 2 F3U,}  
    )h-Qi#{  
    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: swv 1>52{  
    1. 在FRED脚本编辑界面找到参考. 5\Sm^t|Tx  
    2. 找到Matlab Automation Server Type Library J%c4-'l  
    3. 将名字改为MLAPP t(FI Bf3  
    |T:' G  
    t><AaYij_  
    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。 X_Vj&{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: C<Q;3w`#1j  
    1. 创建Matlab服务器。 j}NGyS" =  
    2. 移动探测面对于前一聚焦面的位置。 Jwzkd"D  
    3. 在探测面追迹光线  qOO2@c  
    4. 在探测面计算照度 dLQV>oF  
    5. 使用PutWorkspaceData发送照度数据到Matlab _Wn5* Pi%Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {U?UM  
    7. 用Matlab画出照度数据 N0EJHS,>e  
    8. 在Matlab计算照度平均值 ]i\C4*  
    9. 返回数据到FRED中 >q0c!,Ay
