    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。 7<*,O&![|  
    ;d .gVR_V  
    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: g5;Ig  
    enableservice('AutomationServer', true) Zet80|q  
    enableservice('AutomationServer') +w2 `  
    l`A e&nc6  
    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 =3Ohy,5L  
     \62!{  
    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: $!vK#8-&{  
    1. 在FRED脚本编辑界面找到参考. "?G?G'yK>  
    2. 找到Matlab Automation Server Type Library P#|}]oG%  
    3. 将名字改为MLAPP )&$mFwf

    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。 goOw.~dZ'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: h-]c   
    1. 创建Matlab服务器。 $q##Tys  
    2. 移动探测面对于前一聚焦面的位置。 HF<h-gX  
    3. 在探测面追迹光线 e0M'\'J  
    4. 在探测面计算照度 y q!{\@-  
    5. 使用PutWorkspaceData发送照度数据到Matlab v"l8[::  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 XE8%t=V!c$  
    7. 用Matlab画出照度数据 $>zqCi2tB<  
    8. 在Matlab计算照度平均值 LMNmG]#!  
    9. 返回数据到FRED中 mgTzwE_\
