    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。 F-/z@tM  
    BX?DI-o^h  
    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: "Au4&Fu  
    enableservice('AutomationServer', true) BTkx}KK  
    enableservice('AutomationServer') 3^UdB9j;  
    '0D$C},^|8  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 1(o\GI3:  
    ,s~l; Gkj  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Mh7m2\fLbd  
    1. 在FRED脚本编辑界面找到参考. m8fj\,X  
    2. 找到Matlab Automation Server Type Library ]W5*R07  
    3. 将名字改为MLAPP 2$Mnwxfk

    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。 }YDi/b7

    4. 在探测面计算照度 RM|J |R  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6j6CA?|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #|b*l/t8  
    7. 用Matlab画出照度数据 {fXkbMO|  
    8. 在Matlab计算照度平均值 vXDs/,`r  
    9. 返回数据到FRED中 <VxA&bb7c
