    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。 ID_|H?.  
    cS. 7\0$  
    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: {-:4O\/  
    enableservice('AutomationServer', true) zWP.1 aA&  
        enableservice('AutomationServer') K*J4&5?/  
    vCYSm  0  
    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 "P>$=X~Zi  
    2D\x-!l/  
    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: v3=&{}+j.  
    1. 在FRED脚本编辑界面找到参考. )M&I)In'  
    2. 找到Matlab Automation Server Type Library >e5q2U   
        3. 将名字改为MLAPP )Gu0i7iN

         !HT>  
    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。 KqG/a

    5. 使用PutWorkspaceData发送照度数据到Matlab a{%52B"  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 `gBXeG2fn  
    7. 用Matlab画出照度数据 2:6Y83  
    8. 在Matlab计算照度平均值 inq4CGY  
    9. 返回数据到FRED中 {YxSH %
