    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。 z',f'3+  
    R0#'t+7^  
    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: y]okOEV0  
    enableservice('AutomationServer', true) vn+~P9SHQ  
    enableservice('AutomationServer') [ KDNKK  
    }*P?KV (  
    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 wpI"kk_@@

    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: IkuE|  
    1. 在FRED脚本编辑界面找到参考.  9+ A~(  
    2. 找到Matlab Automation Server Type Library ]&?8l:3-G  
    3. 将名字改为MLAPP ]i/Bq!d l

    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。 }0C v J4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >rYkVlv  
    1. 创建Matlab服务器。 ;LC?3.  
    2. 移动探测面对于前一聚焦面的位置。 U;=1v:~d  
    3. 在探测面追迹光线 _7;D0l  
    4. 在探测面计算照度 4 'DEdx,&f  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ie[DTy  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 z+K1[1SM  
    7. 用Matlab画出照度数据 !A:d9 k  
    8. 在Matlab计算照度平均值 Nwg?(h#  
    9. 返回数据到FRED中 F@b=S0}K
