    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。 =GM!M@~,Ab  
    o<P%|>qX  
    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: 8gBqur{  
    enableservice('AutomationServer', true) &"C1XM  
    enableservice('AutomationServer') n3b@ 6V1_  
    w6Tb<ja  
    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 (DK pJCx  
    PD/JXExK  
    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: [AX).b  
    1. 在FRED脚本编辑界面找到参考. Z{_'V+Q1  
    2. 找到Matlab Automation Server Type Library <)n   
    3. 将名字改为MLAPP PLo.q|%

    9R;s;2$.  
    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。 7P|(j<JX6'

    现在将脚本代码公布如下,此脚本执行如下几个步骤: <!OP b(g2  
    1. 创建Matlab服务器。 'T|.<u@~  
    2. 移动探测面对于前一聚焦面的位置。 ,}FYY66K  
    3. 在探测面追迹光线 S-f3rL[?  
    4. 在探测面计算照度 <U,T*Ql1x  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,CM$A}7[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i,yK&*>JJ  
    7. 用Matlab画出照度数据 U;V. +onv  
    8. 在Matlab计算照度平均值 =C3l:pGMB;  
    9. 返回数据到FRED中 At bqj?
