    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。 Wf&G9Be?8  
    |RbUmuj  
    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: 56~da ){gd  
    enableservice('AutomationServer', true) B )3SiU  
        enableservice('AutomationServer') K+aJ`V  
    oq m{<g?2  
    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 a!6OE"?QQ  
    W3{5Do.h  
    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: )8A=yrTIT  
    1. 在FRED脚本编辑界面找到参考. ^/RM;`h0  
    2. 找到Matlab Automation Server Type Library !C)>  
        3. 将名字改为MLAPP {7MgN'4  
         (UiH3Q9C]%  
         $@ #G+QQ_  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 #$ raUNr

    3. 在探测面追迹光线 Q,LWZw~"  
    4. 在探测面计算照度 7*8nUq  
    5. 使用PutWorkspaceData发送照度数据到Matlab &wWGZ~T  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ovRCF(Og,  
    7. 用Matlab画出照度数据 ok=E/77`  
    8. 在Matlab计算照度平均值 # JT%]!
