    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。 h`1<+1J9  
    ;]=w6'dP!  
    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: Wmcd{MOS  
    enableservice('AutomationServer', true) ]&Y^  
        enableservice('AutomationServer') Z8xB a0  
    1r$-Uh  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 G)}[!'<rR  
    G|1.qHP[F  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: X=]utn  
    1. 在FRED脚本编辑界面找到参考. Kh$"5dy  
    2. 找到Matlab Automation Server Type Library d8jH?P-"  
        3. 将名字改为MLAPP #c@&mus  
         s)qrlv5H  
         ;Hk3y+&]a  
    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。 UcQ]n0J=Z

    3. 在探测面追迹光线 g3NUw/]#  
    4. 在探测面计算照度 P1LOj  
    5. 使用PutWorkspaceData发送照度数据到Matlab o(jLirnk  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 !mUJ["#  
    7. 用Matlab画出照度数据 fIQ, }>  
    8. 在Matlab计算照度平均值 CipDeqau2  
    9. 返回数据到FRED中 $Xlr@)%
