    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。 cWIX!tc8  
    'qBg^c  
    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: CFD& -tED&  
    enableservice('AutomationServer', true) <rc3&qmd  
        enableservice('AutomationServer') DmAMr=p  
    u->UV:u  
    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 !?B9 0(  
    d#7 z N  
    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: GIQ/gM?Pv  
    1. 在FRED脚本编辑界面找到参考. M@@"-dy  
    2. 找到Matlab Automation Server Type Library Eugt~j3  
        3. 将名字改为MLAPP YBQO]3f

         2#'{Q4K  
    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。 +GMM&6<

    4. 在探测面计算照度 pc}Q_~e  
    5. 使用PutWorkspaceData发送照度数据到Matlab e $QX?y .  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 X tZ0z?  
    7. 用Matlab画出照度数据 M5 ep\^
