    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。 B| 0s4E  
    !=Kay^J~.  
    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: [ sO<6?LY  
    enableservice('AutomationServer', true) l<MCmKuYp  
    enableservice('AutomationServer') U%PMV?L{  
    ?[4khQt  
    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 -Fw4;&>

    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: #O974f8  
    1. 在FRED脚本编辑界面找到参考. @Q1F#IU  
    2. 找到Matlab Automation Server Type Library \#oV<MR  
    3. 将名字改为MLAPP fdEj#Ux<H  
    qx<zX\qI6n  
    JA(q>>4  
    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。 UmI@":|-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $6?KH7lA  
    1. 创建Matlab服务器。 u'n%BVt   
    2. 移动探测面对于前一聚焦面的位置。 )mZy>45  
    3. 在探测面追迹光线 ?(L? X&)v  
    4. 在探测面计算照度 %fSk "%u%<  
    5. 使用PutWorkspaceData发送照度数据到Matlab cXE y>U|/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1bAp{u&  
    7. 用Matlab画出照度数据 b({b5z.A  
    8. 在Matlab计算照度平均值 +CHO0n  
    9. 返回数据到FRED中 8lb `
