    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。 %aNm j)L  
    B%8@yS  
    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: fd )v{OC  
    enableservice('AutomationServer', true) +aOdaNcI  
        enableservice('AutomationServer') d1cp=RbC  
    E y:68yU  
    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 Fx:38Ae  
    vxmX5.  
    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: J%CCUl2  
    1. 在FRED脚本编辑界面找到参考. Og1-LP|X  
    2. 找到Matlab Automation Server Type Library KZ%i&w#<  
        3. 将名字改为MLAPP fbh,V%t7  
         QCb D^  
         x-[ItJ% l  
    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。 H{Ewj_L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: OyO]; Yk  
    1. 创建Matlab服务器。 i47LX;}  
    2. 移动探测面对于前一聚焦面的位置。 y > =Y  
    3. 在探测面追迹光线 vaB ql(?'2  
    4. 在探测面计算照度 BEOPZ[Q|c  
    5. 使用PutWorkspaceData发送照度数据到Matlab Wq4<9D  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Rf!v{\  
    7. 用Matlab画出照度数据 <L]Gk]k_R  
    8. 在Matlab计算照度平均值 D&):2F^9.  
    9. 返回数据到FRED中 N0p6xg~
