    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。 JH.XZM&  
    CQWXLQED>  
    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: ]\M{Abqd{  
    enableservice('AutomationServer', true) _EMI%P& s  
    enableservice('AutomationServer') ' ##?PQ*u  
    q}@L"a`  
    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 Z@Rm^g]o

    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: {xTq5`&gT  
    1. 在FRED脚本编辑界面找到参考. ^N={4'G)  
    2. 找到Matlab Automation Server Type Library f-F=!^.  
    3. 将名字改为MLAPP <j'K7We/tP

    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。 {>ba7-Cy+y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |Rf j 0+  
    1. 创建Matlab服务器。 WESD^FK  
    2. 移动探测面对于前一聚焦面的位置。 UPfE\KN+p#  
    3. 在探测面追迹光线 E/:U,u{  
    4. 在探测面计算照度 bbC@  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2y!n c%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 rp@:i _]  
    7. 用Matlab画出照度数据 mE<_oRM)  
    8. 在Matlab计算照度平均值 TZgtu+&  
    9. 返回数据到FRED中 ;dzy 5o3
