    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。 R6xJw2;_  
    "8BZj;yS  
    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: p7Q}xx  
    enableservice('AutomationServer', true) <i!:{'%  
    enableservice('AutomationServer') $,s"c(pv[,  
    { Rd){ky@  
    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 q'% cVM  
    #9's^}i  
    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: (**k4c,  
    1. 在FRED脚本编辑界面找到参考. }$5e!t_K  
    2. 找到Matlab Automation Server Type Library U?WS\Jji3!  
    3. 将名字改为MLAPP +nOa&d\

    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。 UtpK"U$XOU

    1. 创建Matlab服务器。 n[`KhRN  
    2. 移动探测面对于前一聚焦面的位置。 RaX :&PE  
    3. 在探测面追迹光线 /XeCJxo8  
    4. 在探测面计算照度 gf]k@-)  
    5. 使用PutWorkspaceData发送照度数据到Matlab J+]W*?m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $+%eLx*

    8. 在Matlab计算照度平均值 m })EYs1  
    9. 返回数据到FRED中 1dE |q{
