    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。 3\jcq@N  
    bAa+MB#A  
    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: & 0*=F%Fd  
    enableservice('AutomationServer', true) n!K<g.tjW  
    enableservice('AutomationServer') !?~>f>js_l  
    ADQ#qA,/  
    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 vtS [Tkk|A  
    m|5yET  
    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: gZD,#D.hR  
    1. 在FRED脚本编辑界面找到参考. T+y3Ph--^  
    2. 找到Matlab Automation Server Type Library pl{Pur ;i  
    3. 将名字改为MLAPP i$:\,  
    $stBB  
    _Bh ^<D-  
    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。 R} #6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pg%'_+$~m  
    1. 创建Matlab服务器。 P{-f./(JD  
    2. 移动探测面对于前一聚焦面的位置。 ARD&L$AX  
    3. 在探测面追迹光线 OEN!~-u  
    4. 在探测面计算照度 }LaRa.3  
    5. 使用PutWorkspaceData发送照度数据到Matlab SbLx`]rI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ;be2sTo  
    7. 用Matlab画出照度数据 W\tSXM-Hg  
    8. 在Matlab计算照度平均值 3',|HA /x  
    9. 返回数据到FRED中 JDyP..Dt
