    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。 7 D#y  
    mSxn7LG  
    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: L4g%o9G  
    enableservice('AutomationServer', true) CPP~,E_  
        enableservice('AutomationServer') SE]5cJ'>  
    chE!,gik  
    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 Kg$RT?q-C6  
    6&eXQl  
    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: /;Tc]  
    1. 在FRED脚本编辑界面找到参考. ;X,u   
    2. 找到Matlab Automation Server Type Library &P|[YP37_  
        3. 将名字改为MLAPP E s5: S#  
         xZ9:9/Vg  
         'cXdc  
    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。 @ivd|*?k0

    3. 在探测面追迹光线 %x$U(I}  
    4. 在探测面计算照度 S }`sp[6  
    5. 使用PutWorkspaceData发送照度数据到Matlab H0Pxw P>q  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 MePD:;mm^  
    7. 用Matlab画出照度数据 ;"wCBuXcu  
    8. 在Matlab计算照度平均值 -Ks>s  
    9. 返回数据到FRED中 } p'ZMj&
