    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。 @Z2^smf  
    #Q'j^y 7=z  
    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: 9mRP%c#(  
    enableservice('AutomationServer', true) R;3n L[{U  
    enableservice('AutomationServer') >7,?X_:A-1  
    5VZZk%oy  
    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 F0x'^Z}Q;  
    'B yB1NL  
    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: A} v;uNS]  
    1. 在FRED脚本编辑界面找到参考. _ 2 oZhJ  
    2. 找到Matlab Automation Server Type Library :Fh#"<A&&  
    3. 将名字改为MLAPP (bp4ly^

    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。 T7R,6 qt

    3. 在探测面追迹光线 &t:~e" 5<  
    4. 在探测面计算照度 AjD? _DPc  
    5. 使用PutWorkspaceData发送照度数据到Matlab *b8AN3!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]8f$&gw&A  
    7. 用Matlab画出照度数据 %sCG}? y  
    8. 在Matlab计算照度平均值 _qa9wK/  
    9. 返回数据到FRED中 10IX8 4
