    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。 vZhC_G+tGd  
    l;F\s&^  
    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: VS.~gHx  
    enableservice('AutomationServer', true) S)`%clN}J  
        enableservice('AutomationServer') xLX2F   
    e'"2yA8dh"  
    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 7I\qEr57  
    ( x)}k&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: ::goqajV  
    1. 在FRED脚本编辑界面找到参考. X8m@xFW}  
    2. 找到Matlab Automation Server Type Library P_7QZ0k/  
        3. 将名字改为MLAPP U1oZ\Mh  
         M{(g"ha  
         'c]Fhe fb  
    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。 [2~^~K

    4. 在探测面计算照度 p"'knZ G  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8D]&wBR:  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 MP LgE.n  
    7. 用Matlab画出照度数据 :r+BL@9  
    8. 在Matlab计算照度平均值 ,_wpYTl*X  
    9. 返回数据到FRED中 r]+/"~a
