    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。 )WsR 8tk  
    J+l#!gk$!  
    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: Oar%LSkPRz  
    enableservice('AutomationServer', true) 4"#F =f0  
    enableservice('AutomationServer') &Xi] 0\M)  
    ~~}8D"  
    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 h>ZU67-   
    ?I"FmJ;  
    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: 9F7}1cH7g@  
    1. 在FRED脚本编辑界面找到参考. >OKc\m2%Q  
    2. 找到Matlab Automation Server Type Library 4@=[r Zb9  
    3. 将名字改为MLAPP y(X^wC

    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。 YM#J_sy@J.

    4. 在探测面计算照度 r o8C^d]  
    5. 使用PutWorkspaceData发送照度数据到Matlab BC R]K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +de5y]1H,|  
    7. 用Matlab画出照度数据 [a7S?%>Bh  
    8. 在Matlab计算照度平均值 A>6_h1  
    9. 返回数据到FRED中 b6g/SIae
