    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。 <sq@[\l}a  
    y*Wl(w3  
    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: /IN/SZx  
    enableservice('AutomationServer', true) ^~%z Plv  
    enableservice('AutomationServer') *S@0o6v  
    -N[Q*;h|  
    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 u2xb^vu  
    \aG:l.IM0  
    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: Qv@Z#  
    1. 在FRED脚本编辑界面找到参考. +k4 SN  
    2. 找到Matlab Automation Server Type Library kf<5`8  
    3. 将名字改为MLAPP *"D8E^9  
    ?=h{`Ci^ $  
    o-jF?9m  
    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。 W}U-u{Z

    3. 在探测面追迹光线 0UB,EI8   
    4. 在探测面计算照度 C%csQ m  
    5. 使用PutWorkspaceData发送照度数据到Matlab VfiMR%i}  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !~&vcz0>)9  
    7. 用Matlab画出照度数据 >9.xFiq<  
    8. 在Matlab计算照度平均值 ^^I3%6UY
