    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。 ai3wSUYJi  
    &Z.zem?n  
    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)RCo}f  
    enableservice('AutomationServer', true) lY.{v]i }  
        enableservice('AutomationServer') CDNh9`  
    ?`,Rkg0fe  
    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 Cwb }$=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: T6P9Icv?@7  
    1. 在FRED脚本编辑界面找到参考. ^lt;K{  
    2. 找到Matlab Automation Server Type Library eJ=K*t|  
        3. 将名字改为MLAPP 62}rZVJq  
         -W#-m'Lvu  
         q1|! oQ  
    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。 /C'dW

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;RmL'  
    1. 创建Matlab服务器。 q=_&izmE'7  
    2. 移动探测面对于前一聚焦面的位置。 1L4-hYtCj  
    3. 在探测面追迹光线 2tEA8F~k  
    4. 在探测面计算照度 "K!9^!4&  
    5. 使用PutWorkspaceData发送照度数据到Matlab /+11`B09  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 -F]0Py8(  
    7. 用Matlab画出照度数据 O%$XgEJ8p  
    8. 在Matlab计算照度平均值 !6yyX}%o  
    9. 返回数据到FRED中 S7I8BS[*v
