    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。 !ni>\lZ  
    #epy%>  
    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: 9M'DC^x*T  
    enableservice('AutomationServer', true) ;#/0b{XFj  
    enableservice('AutomationServer') EB,4PEe:  
    +pp9d-n  
    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 jg_n7  
    C-w5KW  
    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: NY!jwb@%  
    1. 在FRED脚本编辑界面找到参考. x8"#!Pw:`"  
    2. 找到Matlab Automation Server Type Library Uf$i3  
    3. 将名字改为MLAPP |" 7 Y52d  
    6ep>hS4A&  
    Vz"u>BP3~  
    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。 /;oqf4MF

    现在将脚本代码公布如下,此脚本执行如下几个步骤: CDdkoajBa  
    1. 创建Matlab服务器。 Eju~}:Lo  
    2. 移动探测面对于前一聚焦面的位置。 j*3}1L4P  
    3. 在探测面追迹光线 7bF*AYM  
    4. 在探测面计算照度 f/y`  
    5. 使用PutWorkspaceData发送照度数据到Matlab v>m n/a  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?WFh',`:  
    7. 用Matlab画出照度数据 |W7rr1]~S  
    8. 在Matlab计算照度平均值 cdTsRS;E  
    9. 返回数据到FRED中 s'u(B]E
