    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。 ^5TSo&qZ  
    96aA2s1  
    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: u7>b}+ak&  
    enableservice('AutomationServer', true) nAn/Vu  
    enableservice('AutomationServer') #LlHsY530N  
    ~ \tI9L?|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 G#/}_P

    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: @SA*7[?P  
    1. 在FRED脚本编辑界面找到参考. >W"gr]R<  
    2. 找到Matlab Automation Server Type Library E6n3[Z  
    3. 将名字改为MLAPP  "Mgx5d  
    <}b`2/wP  
    ^yUel.N5"  
    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。 ;bVC7D~~4w

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &^e%gU8!\  
    1. 创建Matlab服务器。 gB@Xi*  
    2. 移动探测面对于前一聚焦面的位置。 ~<Z;)e  
    3. 在探测面追迹光线 @-bX[}.  
    4. 在探测面计算照度 6k;__@B,  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6_/691  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >*H>'O4  
    7. 用Matlab画出照度数据 fk)ts,p?  
    8. 在Matlab计算照度平均值 I%^Ks$<"  
    9. 返回数据到FRED中 )W)m?%
