    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。 $_F_%m"\  
    #r#[&b  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: TBt5Nqks-  
    enableservice('AutomationServer', true) cjL)M=pIS  
    enableservice('AutomationServer') HX2u{2$  
    {Phq39g  
    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}k:wzZ@  
    %Lh%bqGz  
    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: D;P=\i>9-  
    1. 在FRED脚本编辑界面找到参考. ?+.mP]d_  
    2. 找到Matlab Automation Server Type Library /p<9C?  
    3. 将名字改为MLAPP inU5eronuj

    O4X03fUx  
    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。 <KX9>e

    4. 在探测面计算照度 -7&ywgxl  
    5. 使用PutWorkspaceData发送照度数据到Matlab h |]cZMGo  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 26/<\{q~  
    7. 用Matlab画出照度数据 k{mBG9[z  
    8. 在Matlab计算照度平均值 ML>M:Ik+
