    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。 mW{uChHP  
    ,<!*@xy7v  
    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: lO|LvJyx  
    enableservice('AutomationServer', true) "6IZf>N@#  
    enableservice('AutomationServer') Z&?4<-@6\p  
    \: F$7 *Ne  
    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 g||EjCsp

    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: b 1.S21  
    1. 在FRED脚本编辑界面找到参考. F5+F O^3E  
    2. 找到Matlab Automation Server Type Library T^MY w  
    3. 将名字改为MLAPP wQhuU

    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。 *tT}N@<%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )uAY_()/  
    1. 创建Matlab服务器。 _vb'3~'S  
    2. 移动探测面对于前一聚焦面的位置。 ts(u7CJd  
    3. 在探测面追迹光线 bBc<p{  
    4. 在探测面计算照度 *w. ":\P]  
    5. 使用PutWorkspaceData发送照度数据到Matlab t zd#9 #  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R+ \%  
    7. 用Matlab画出照度数据 ^HR8.9^[1u  
    8. 在Matlab计算照度平均值 b{-"GqMO  
    9. 返回数据到FRED中 ( ./MFf
