    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。 yH%+cmp7  
    (D m"e`  
    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: u)`|q_y+8  
    enableservice('AutomationServer', true) `u~  
    enableservice('AutomationServer') z<6P3x|  
    +){a[@S@x  
    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 9]@J*A}=l  
    ;"Y;l=9_  
    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: v^W?o}W  
    1. 在FRED脚本编辑界面找到参考. #)A?PO2  
    2. 找到Matlab Automation Server Type Library p@8krOo`  
    3. 将名字改为MLAPP #IaBl?}r^  
    N~5WA3xd  
    ./nYXREO|  
    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。 v?D kDnta

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;D"P9b]9$  
    1. 创建Matlab服务器。 4 uy@ {  
    2. 移动探测面对于前一聚焦面的位置。 8U<.16+5Q  
    3. 在探测面追迹光线 _jrA?pY  
    4. 在探测面计算照度 <]Pix )  
    5. 使用PutWorkspaceData发送照度数据到Matlab wGzXp5 dl  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xUo)_P\_  
    7. 用Matlab画出照度数据 Wytvs*\`  
    8. 在Matlab计算照度平均值 m0A@jWgd  
    9. 返回数据到FRED中 M-Z6TL
