    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。 &4 #%xg  
    +nim47  
    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: ,?IXfJ`c  
    enableservice('AutomationServer', true) ld):Am}/o  
        enableservice('AutomationServer') {K}Dpy  
    qh&q <M  
    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 g{uiY|  
    "%S-(ue:  
    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: g1_z=(i`Z  
    1. 在FRED脚本编辑界面找到参考. a/H5Y,b>  
    2. 找到Matlab Automation Server Type Library 5wE6gRJ  
        3. 将名字改为MLAPP J><hrZ  
         g& f)WQ(  
         }NRt:JC  
    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。 ;l<Hen*

    4. 在探测面计算照度 Io>U-Zd\>  
    5. 使用PutWorkspaceData发送照度数据到Matlab l0qHoM,1Y[  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 +lZ-xU1  
    7. 用Matlab画出照度数据 c* ~0R?  
    8. 在Matlab计算照度平均值 $:1/`m19  
    9. 返回数据到FRED中 lw?C:-m
