    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。 %E1~I\n:F  
    KPW: r#d  
    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: iA^w2K  
    enableservice('AutomationServer', true) UT+\IzL  
    enableservice('AutomationServer') PwF}yx kI  
    '  AeU  
    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 l:+tl/

    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: F`Q,pBl1p6  
    1. 在FRED脚本编辑界面找到参考. H.Jcp|k[;  
    2. 找到Matlab Automation Server Type Library ^%go\ C ;  
    3. 将名字改为MLAPP p*Q"<@n  
    k]R O=/ ?M  
    4$IPz7  
    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。 Ug_zyfr

    现在将脚本代码公布如下,此脚本执行如下几个步骤: gQ?>%t]  
    1. 创建Matlab服务器。 px4Z  
    2. 移动探测面对于前一聚焦面的位置。 WNm,r>6m  
    3. 在探测面追迹光线 2Q9s?C   
    4. 在探测面计算照度 EHzU`('?[  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9!bD|-6y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 M/UJb1<  
    7. 用Matlab画出照度数据 'QCvN b6  
    8. 在Matlab计算照度平均值 yc%AkhX*  
    9. 返回数据到FRED中 Kwh3SU=L}
