    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。 Nx z ,/d  
    v A~hkkj{  
    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: Y %8QFM  
    enableservice('AutomationServer', true) scwlW b<N  
    enableservice('AutomationServer') I65GUX#DV  
    MRu+:Y=K  
    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 <rxem(PPu  
    e$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: .gg0:  
    1. 在FRED脚本编辑界面找到参考. ;%9ZL[-  
    2. 找到Matlab Automation Server Type Library 5|z[%x~f  
    3. 将名字改为MLAPP L6qA=b~iz  
    jZ yh   
    ]2 N';(R  
    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。 X~!?t }

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w` :KexD+  
    1. 创建Matlab服务器。 <!$Cvx\U  
    2. 移动探测面对于前一聚焦面的位置。 q\Z1-sl~s  
    3. 在探测面追迹光线 :D-vE7  
    4. 在探测面计算照度 K?WqAVK  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]z NL+]1_  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LnIJ wD  
    7. 用Matlab画出照度数据 Cvy;O~)  
    8. 在Matlab计算照度平均值 '.yr8  
    9. 返回数据到FRED中 <3OV
