    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。 dbF9%I@  
    E.^u:0:P  
    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: =H^~"16  
    enableservice('AutomationServer', true) \tdYTb.  
    enableservice('AutomationServer') ;)sC{ "Jb  
    B<~BX [  
    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 8P&z@E{y  
    gV'=u z v  
    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: 9$%S<v  
    1. 在FRED脚本编辑界面找到参考. $us7fuKE  
    2. 找到Matlab Automation Server Type Library +Lo,*  
    3. 将名字改为MLAPP ^HHT>K-m

    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。 QR$m i1Vv\

    1. 创建Matlab服务器。 &*~_ "WyU

    3. 在探测面追迹光线 <S0gIg`)  
    4. 在探测面计算照度 3:b5#c?R-  
    5. 使用PutWorkspaceData发送照度数据到Matlab '9AYE"7Ydk  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 vnX~OVz2  
    7. 用Matlab画出照度数据 5g2:o^  
    8. 在Matlab计算照度平均值 _ n4C~  
    9. 返回数据到FRED中 mf2Qu
