    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。 Lmy ^/P%  
    7kBULeBn|  
    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: G?Y2 b  
    enableservice('AutomationServer', true) x}.Q9L  
    enableservice('AutomationServer') w,\#)<boyb  
    yTDlDOmV!  
    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 <uugT9By

    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: ,3k"J4|d  
    1. 在FRED脚本编辑界面找到参考. }ug|&25D  
    2. 找到Matlab Automation Server Type Library "tga FtC=w  
    3. 将名字改为MLAPP Vo%MG.IPB

    2WjQ-mM#  
    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。 FTtGiGd|Zy

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $1N_qu  
    1. 创建Matlab服务器。 qA<PF+f  
    2. 移动探测面对于前一聚焦面的位置。 #Nt? 4T<  
    3. 在探测面追迹光线 G)b6Rit  
    4. 在探测面计算照度 q%=`PCty  
    5. 使用PutWorkspaceData发送照度数据到Matlab UW+|1Bj_:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 T jO}P\p  
    7. 用Matlab画出照度数据 =N,Mmz%  
    8. 在Matlab计算照度平均值 A f@IsCOJ  
    9. 返回数据到FRED中 8X`Gm!)
