    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。 0d%p<c  
    5,pKv  
    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: w,'"2^Cwy  
    enableservice('AutomationServer', true) 3O W) %  
    enableservice('AutomationServer') 6axDuwQ  
    cjd Z.jR2  
    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 H,F/u&O  
    &vy/Vd  
    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: @y#QHJ.j  
    1. 在FRED脚本编辑界面找到参考. 0^27grU>   
    2. 找到Matlab Automation Server Type Library le*1L8n$'  
    3. 将名字改为MLAPP :-I~-Yj  
    ,s?7EHtC  
    Pd,+= ML  
    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。 D9#?l <D

    现在将脚本代码公布如下,此脚本执行如下几个步骤: t:|+U:! >  
    1. 创建Matlab服务器。 }Z|uLXaz  
    2. 移动探测面对于前一聚焦面的位置。 yWs_Z6b  
    3. 在探测面追迹光线 HhmC+3w.7  
    4. 在探测面计算照度 f-V8/  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?Q~6\xA  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R"au8f.  
    7. 用Matlab画出照度数据 @Gs*y1  
    8. 在Matlab计算照度平均值 1-Fz#v7p  
    9. 返回数据到FRED中 NW.<v /?=,
