    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。 J3lG"Ww  
    ) 8x:x7?  
    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: `Ct'/h{  
    enableservice('AutomationServer', true) <4l.s  
    enableservice('AutomationServer') To#E@Nw  
    WIEx '{  
    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 t`<}UWAH+

    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: koncWyW  
    1. 在FRED脚本编辑界面找到参考. o;M.Rt\A  
    2. 找到Matlab Automation Server Type Library e?^ \r)1  
    3. 将名字改为MLAPP )d770Xg+

    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。 q9W~7

    4. 在探测面计算照度 Lf,CxZL5  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]+}ZfHp  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 `DgaO-Dg3  
    7. 用Matlab画出照度数据 ou<S)_|Iu  
    8. 在Matlab计算照度平均值 RL7C YB  
    9. 返回数据到FRED中 936Ff*%(l
