    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。 nXx6L!HJ#  
    nF|#@O`1  
    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: g(ZeFOn  
    enableservice('AutomationServer', true) j<`I\Pmv  
        enableservice('AutomationServer')  ]2hF!{wc  
    ,-w-su=J_  
    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 K,`).YK  
    R[mH35D/  
    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: 7j9D;_(.^$  
    1. 在FRED脚本编辑界面找到参考. 0"wbcAh)  
    2. 找到Matlab Automation Server Type Library C:|q'"F  
        3. 将名字改为MLAPP WZ-4^WM=!  
         L8,H9T#e  
         X67C;H+  
    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。 @d8&3@{R^

    4. 在探测面计算照度 .ruz l(6  
    5. 使用PutWorkspaceData发送照度数据到Matlab Thht_3_C,f  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 bc0)'a\  
    7. 用Matlab画出照度数据 mh!N^[=n  
    8. 在Matlab计算照度平均值 eR#gG^o8  
    9. 返回数据到FRED中 'O\d<F.c$2
