    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。 \Y>!vh X  
    yV'<l .N  
    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: ogOUrJ}P  
    enableservice('AutomationServer', true) =GP~h*5es  
        enableservice('AutomationServer') 2[O\"a%  
    j06Xz\c  
    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 _ ?\4k{ET  
    P B W.nm  
    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: e5 "?ol0  
    1. 在FRED脚本编辑界面找到参考. jkN-(v(T  
    2. 找到Matlab Automation Server Type Library Ykt{]#  
        3. 将名字改为MLAPP Fz3QSr7FU

    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。 zUe)f~4

    4. 在探测面计算照度 3 zF"GT  
    5. 使用PutWorkspaceData发送照度数据到Matlab e%B;8)7  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 P ]prrKZe,  
    7. 用Matlab画出照度数据 ssWSY(j]
