    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。 n~8-+$6OR  
    )qn =  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: <gZC78}E  
    enableservice('AutomationServer', true) Fng":28o  
        enableservice('AutomationServer') I:]s/r7  
    b&*^\hY9b  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 X z2IAiAs'  
    JXftQOn  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: :&2RV_$>=  
    1. 在FRED脚本编辑界面找到参考. e l'^9K  
    2. 找到Matlab Automation Server Type Library VaZS_ qGe:  
        3. 将名字改为MLAPP 6@wnF>'/\  
         H }uT'  
         [uc;M6o}?  
    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。 gEO#-tMjOQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |I^\|5  
    1. 创建Matlab服务器。 dB<BEe\$g.  
    2. 移动探测面对于前一聚焦面的位置。 n4>  
    3. 在探测面追迹光线 6b-d#H/1Y  
    4. 在探测面计算照度 \&2GLBKpe  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5|r3i \  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 <Sm =,Sw  
    7. 用Matlab画出照度数据 C(}9  
    8. 在Matlab计算照度平均值 ^^jF*)DT@  
    9. 返回数据到FRED中 H3QAIsGS
