    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。 ( G~ME>  
    nt@uVwfQ  
    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: dGUiMix{N  
    enableservice('AutomationServer', true) 4b+_|kYb  
        enableservice('AutomationServer') *to#ZMR;!  
    C)~%(< D  
    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 s )Xz}QPK.  
    (:^YfG~e  
    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: Y5y7ONcn  
    1. 在FRED脚本编辑界面找到参考. !}5+hj!6  
    2. 找到Matlab Automation Server Type Library 36Lf8~d4"h  
        3. 将名字改为MLAPP EN__C$  
         |"[;0)dw^  
         3v&Shb?xb;  
    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。 YV'B*arIA

    4. 在探测面计算照度 )`S5>[6  
    5. 使用PutWorkspaceData发送照度数据到Matlab (=j/"Mb  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 =@&>r5W1
