    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。 X4E%2-m@'  
    k+Czj  
    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: NzSoqh{R  
    enableservice('AutomationServer', true) C:C}5<fk x  
    enableservice('AutomationServer') cy3B({PLy  
    Id|L`  w  
    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 U4-g^S[  
    \$\ENQ;Nk  
    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: TbGn46!:  
    1. 在FRED脚本编辑界面找到参考. ^,8)iV0j_  
    2. 找到Matlab Automation Server Type Library o .G!7  
    3. 将名字改为MLAPP _:C9{aEZb

    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。 J/GSceHF

    4. 在探测面计算照度 -VTkG]{`Ir  
    5. 使用PutWorkspaceData发送照度数据到Matlab tj4VWJK  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !Kj,9NX{U  
    7. 用Matlab画出照度数据 M&U j^K1  
    8. 在Matlab计算照度平均值 @$c\d vO
