    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。 -n6e;p]  
    F|?}r3{aJ  
    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: ~f?brQ?  
    enableservice('AutomationServer', true) <l$ vnq  
        enableservice('AutomationServer') w,;ox2  
    O2oF\E_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 O5A]{ W  
    E[Ao*  
    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: G3.\x_;k  
    1. 在FRED脚本编辑界面找到参考. L#`X;:   
    2. 找到Matlab Automation Server Type Library m%)S <L7 l  
        3. 将名字改为MLAPP e@g=wN"@  
         :<,tGYg/!  
         FOS*X  
    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。 Bn*QT:SKC

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (FSa>  
    1. 创建Matlab服务器。 sJm v{wM  
    2. 移动探测面对于前一聚焦面的位置。 (O'O #AD  
    3. 在探测面追迹光线 Q*R9OF  
    4. 在探测面计算照度 ,A>cL#Oe  
    5. 使用PutWorkspaceData发送照度数据到Matlab M#xol/)h  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 :-cqC|Y  
    7. 用Matlab画出照度数据 :<xf'.  
    8. 在Matlab计算照度平均值 ro18%' RRI  
    9. 返回数据到FRED中 #QiNSS
