    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。 L1F###c  
    nF j-<!  
    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: mo*'"/  
    enableservice('AutomationServer', true) }\4p3RQrz  
        enableservice('AutomationServer') /B=l,:TnJ  
    qM*S*,s  
    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 @9<S*  
     s<d!+<  
    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: QnP{$rT  
    1. 在FRED脚本编辑界面找到参考. Me<du& T  
    2. 找到Matlab Automation Server Type Library W[GQ[h  
        3. 将名字改为MLAPP Lb^(E-  
         mw Z'=H  
         [NZ-WU&&LP  
    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。 } m6\C5

    1. 创建Matlab服务器。 HrDTn&/  
    2. 移动探测面对于前一聚焦面的位置。 mHHzCKE,  
    3. 在探测面追迹光线 9,w}Xe=C  
    4. 在探测面计算照度 r/^tzH's  
    5. 使用PutWorkspaceData发送照度数据到Matlab *i%.{ YH  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 mw ?{LT  
    7. 用Matlab画出照度数据 p; F2z;#  
    8. 在Matlab计算照度平均值 e"PMvQ  
    9. 返回数据到FRED中 -}<d(c
