    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。 <B =!ZC=n  
    WA79(B  
    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: `Ef &h V  
    enableservice('AutomationServer', true) Gj(UA1~1  
    enableservice('AutomationServer') D[iIj_CKQ  
    hR3Pa'/i  
    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 ;3k6_ub  
    uH?lj&  
    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: DU: sQS4  
    1. 在FRED脚本编辑界面找到参考. Zjh9jvsW  
    2. 找到Matlab Automation Server Type Library DozC>  
    3. 将名字改为MLAPP  !B\[Q$

    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。 >5!/&D.q

    1. 创建Matlab服务器。 r ,,A%  
    2. 移动探测面对于前一聚焦面的位置。 Fttny]  
    3. 在探测面追迹光线 M B,P#7|  
    4. 在探测面计算照度 hrr;=q$  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,w/f :-y  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6uH1dsD  
    7. 用Matlab画出照度数据 4$+9k;m'  
    8. 在Matlab计算照度平均值 @tLoU%  
    9. 返回数据到FRED中 8Bnw//_pT
