    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。 M y!;N1  
    v807)JwS  
    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: E8.1jCL>{"  
    enableservice('AutomationServer', true) ;Ouu+#s  
    enableservice('AutomationServer') q+)s  
    #Wt1Ph_;  
    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 W"g@*B'|

    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: h@{CMe  
    1. 在FRED脚本编辑界面找到参考. mpzm6I eu  
    2. 找到Matlab Automation Server Type Library +2m\Sv V  
    3. 将名字改为MLAPP uXdR-@80*  
    tj:>o#D  
    t.] e8=dE  
    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。 (Zu8WyT2

    4. 在探测面计算照度 %|3NCyJ*7  
    5. 使用PutWorkspaceData发送照度数据到Matlab XD|vB+j\O  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 E" b" VB
