    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。 c D7FfJ  
    auL^%M|$R  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: c3#q0Ma  
    enableservice('AutomationServer', true) e9:P9Di(b  
    enableservice('AutomationServer') S(w\ZC  
    h)@InYwu7  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Hk9U&j$  
    AerFgQiS  
    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: SX_4=^  
    1. 在FRED脚本编辑界面找到参考. OpQ8\[X+  
    2. 找到Matlab Automation Server Type Library %t[K36,p  
    3. 将名字改为MLAPP "lrA%~3%[P

    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。 wDw<KU1UK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?bI?GvSh  
    1. 创建Matlab服务器。 D:m#d.m  
    2. 移动探测面对于前一聚焦面的位置。 FUqt)YHi  
    3. 在探测面追迹光线 h'!V8'}O?  
    4. 在探测面计算照度  d1bhJK  
    5. 使用PutWorkspaceData发送照度数据到Matlab P7r4ePtLk{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 eXG57<t ON  
    7. 用Matlab画出照度数据 km4g}~N</  
    8. 在Matlab计算照度平均值 Rsn^eR6^  
    9. 返回数据到FRED中 " @)lH
