    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。 KCqqJ}G  
    "dCzWFet  
    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: aC\4}i<  
    enableservice('AutomationServer', true) z1j|E :  
    enableservice('AutomationServer') 3:`XG2'  
    TipHV;|e  
    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 (F5ttQPh  
    ,)#.a%EKA  
    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: -Zy)5NB-tZ  
    1. 在FRED脚本编辑界面找到参考. Jq1 n0O  
    2. 找到Matlab Automation Server Type Library @EZ>f5IO+  
    3. 将名字改为MLAPP d<T%`:s<  
    `iYc<N`  
    0D3OE.$0  
    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。 3E|;r _; 8

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !#}>Hv^N  
    1. 创建Matlab服务器。 >4)g4~'n!  
    2. 移动探测面对于前一聚焦面的位置。 L#j/0IHD  
    3. 在探测面追迹光线 L3c*LL  
    4. 在探测面计算照度 z,Xk\@  
    5. 使用PutWorkspaceData发送照度数据到Matlab i^g~~h F  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /bcY6b=:  
    7. 用Matlab画出照度数据 [ b1hC ~I;  
    8. 在Matlab计算照度平均值 htHv&  
    9. 返回数据到FRED中 ,U=E[X=H
