    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。 ZZ k=E4aae  
    K!:azP,bZ  
    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: :QpuO1Gu  
    enableservice('AutomationServer', true) pv*,gSS  
    enableservice('AutomationServer') -j%,Oo  
    s@9vY\5[9  
    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 mk1bcK9  
    pi /g H  
    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: 8JM&(Q%#  
    1. 在FRED脚本编辑界面找到参考. {aY%gk?y#>  
    2. 找到Matlab Automation Server Type Library p!>oo1&  
    3. 将名字改为MLAPP -}=i 04^  
    3x5JFM  
    ?kWC}k{  
    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。 y<HO:kZ8`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: d p2F  
    1. 创建Matlab服务器。  `dFq:8v  
    2. 移动探测面对于前一聚焦面的位置。 wp#'nO  
    3. 在探测面追迹光线 FuVnk~gq  
    4. 在探测面计算照度 =+ytTQc*ot  
    5. 使用PutWorkspaceData发送照度数据到Matlab TcIcS]w%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 OZx W?wnd  
    7. 用Matlab画出照度数据 aa?w:3  
    8. 在Matlab计算照度平均值 :E_g"_  
    9. 返回数据到FRED中 s>0't
