    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。 !<]%V]5[_  
    `pzp(\lc  
    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: Nh~ Hh(   
    enableservice('AutomationServer', true) s M({u/  
    enableservice('AutomationServer') =,KRZqz  
    .pQH>;k]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 ivC1=+  
    J&S$F:HM  
    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: zcD&xoL\H  
    1. 在FRED脚本编辑界面找到参考. 8Wid.o-U  
    2. 找到Matlab Automation Server Type Library -,Cx|Nl  
    3. 将名字改为MLAPP bCg {z b#  
    aOfL;I  
    y5iLFR3z  
    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。 = ^:TW%O

    4. 在探测面计算照度 B#AAG*Ai8  
    5. 使用PutWorkspaceData发送照度数据到Matlab V(1Ldl'a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G>&=rmK"  
    7. 用Matlab画出照度数据 szMh}q"u  
    8. 在Matlab计算照度平均值 E~_2Jf\U
