    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。 T>2)YOx  
    Adp:O"-H1o  
    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: W|_ @ju  
    enableservice('AutomationServer', true) }\k"azQ`  
    enableservice('AutomationServer') F/sXr(7  
    R| [mp%Q  
    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 "z)dz,&T  
    *T' /5,rX2  
    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: w'oP{=y[  
    1. 在FRED脚本编辑界面找到参考. p(in.Xz  
    2. 找到Matlab Automation Server Type Library p8o ~  
    3. 将名字改为MLAPP Wly-z$\  
    XP~bmh,T,

    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。 a@$U?=\e

    1. 创建Matlab服务器。 ~n9BN'@x  
    2. 移动探测面对于前一聚焦面的位置。 4vKp341B  
    3. 在探测面追迹光线 6*9hAnH  
    4. 在探测面计算照度 t"k6wv;Tq  
    5. 使用PutWorkspaceData发送照度数据到Matlab %m$TV@  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 =Bo(*%  
    7. 用Matlab画出照度数据 A ^@:Ps  
    8. 在Matlab计算照度平均值 L)H' g  
    9. 返回数据到FRED中 K-(k6<h
