    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。 m""+ $  
    $wAR cS  
    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: V8/4:Va7 s  
    enableservice('AutomationServer', true) uE.BB#  
    enableservice('AutomationServer') loIb}8  
    UN'n~d @~  
    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 OKh0m_ )7

    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: 5, $6mU#=  
    1. 在FRED脚本编辑界面找到参考. +(2$YJ35  
    2. 找到Matlab Automation Server Type Library nF'YG+;|@  
    3. 将名字改为MLAPP Ry >y

    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。 2PAu>}W*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :^ywc O   
    1. 创建Matlab服务器。 HF0G=U}i  
    2. 移动探测面对于前一聚焦面的位置。 # ][i!9$  
    3. 在探测面追迹光线 fJlNxdVr  
    4. 在探测面计算照度 `,6|6.8#  
    5. 使用PutWorkspaceData发送照度数据到Matlab di/Q Jrw  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 xnMcxys~  
    7. 用Matlab画出照度数据 O q$_ q  
    8. 在Matlab计算照度平均值 >eA@s}_8  
    9. 返回数据到FRED中 b$klm6nMvm
