    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。 E!P yL>){  
    Os1>kwC  
    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: d|yAs5@  
    enableservice('AutomationServer', true) 2 FW \O0U  
    enableservice('AutomationServer') wL:flH@  
    Pw61_ZZ4B\  
    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 >M/V oV

    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: H?X|(r|+  
    1. 在FRED脚本编辑界面找到参考. g #6E|n  
    2. 找到Matlab Automation Server Type Library 7F{3*`/6  
    3. 将名字改为MLAPP /Bm( `T  
    *N<&GH(j  
    la+[bm< v  
    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。 ]3 l9:|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: I]EbodAyZ,  
    1. 创建Matlab服务器。 HEM9E&rL  
    2. 移动探测面对于前一聚焦面的位置。 aiu5}%U  
    3. 在探测面追迹光线 E`uY1B[c  
    4. 在探测面计算照度 hK,Sf ;5V  
    5. 使用PutWorkspaceData发送照度数据到Matlab _c_[ C*T]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _`:1M2=  
    7. 用Matlab画出照度数据 Ls] g  
    8. 在Matlab计算照度平均值 FK5 <6n,U  
    9. 返回数据到FRED中 AGYc |;
