    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。 IxgnZX4N  
    UmInAH4  
    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: stoBjDS  
    enableservice('AutomationServer', true) %Ljc#AVg  
    enableservice('AutomationServer') SQa.xLU  
    tty 6  
    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 _xUiHX<  
    }_5z(7}3  
    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: /EKfL\3  
    1. 在FRED脚本编辑界面找到参考. !=q {1\#  
    2. 找到Matlab Automation Server Type Library 7d'4"c;*;  
    3. 将名字改为MLAPP B'atwgI0

    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。 )p12SGR5

    3. 在探测面追迹光线 fIWQ+E  
    4. 在探测面计算照度 YN"102CK  
    5. 使用PutWorkspaceData发送照度数据到Matlab p~Dm3^Y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 B:+}^=  
    7. 用Matlab画出照度数据 My_fm?n  
    8. 在Matlab计算照度平均值 Mr/^V,rA  
    9. 返回数据到FRED中 9c#9KCmc
