    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。 F",S}cK*MH  
     /MS*_  
    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: SE0"25\_G  
    enableservice('AutomationServer', true) R/H ?/  
    enableservice('AutomationServer') cZ(7/Pl  
    :!vDX2o)\  
    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 (n&Hjz,Fv  
    .uAO k0^z  
    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: x\ : x`k@  
    1. 在FRED脚本编辑界面找到参考. i!/V wGg  
    2. 找到Matlab Automation Server Type Library @@U'I^iG  
    3. 将名字改为MLAPP {u BpM9KT  
    @Q"%a`mKH  
    "RuH"~o  
    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。 / jI>=:z

    现在将脚本代码公布如下,此脚本执行如下几个步骤: YW@Ad  
    1. 创建Matlab服务器。 ziuhS4k  
    2. 移动探测面对于前一聚焦面的位置。 q9- =>  
    3. 在探测面追迹光线 P |c6V  
    4. 在探测面计算照度 \h6_m)*H4  
    5. 使用PutWorkspaceData发送照度数据到Matlab (r cH\   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w.qpV]9>  
    7. 用Matlab画出照度数据 cdL$T6y  
    8. 在Matlab计算照度平均值 u1y c  
    9. 返回数据到FRED中 + M2|-C
