    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。 !"qEB2r  
    ViC76aJ  
    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: jI pcMN<  
    enableservice('AutomationServer', true) ^rZ+H@p:6  
    enableservice('AutomationServer') FH@e:-*=  
    G`<1>%" F  
    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 4 w

    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: GTX&:5H\t  
    1. 在FRED脚本编辑界面找到参考. m3ZOq B-  
    2. 找到Matlab Automation Server Type Library 9#ay(g  
    3. 将名字改为MLAPP (Y?yGq/

    w@D@,q'x  
    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。 :=KGQ3V~eK

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lJpv  
    1. 创建Matlab服务器。 _-nN( ${{  
    2. 移动探测面对于前一聚焦面的位置。 HAOrwJFqU  
    3. 在探测面追迹光线 Lgw@y!Llij  
    4. 在探测面计算照度 iw6M3g#  
    5. 使用PutWorkspaceData发送照度数据到Matlab Jrrk$0H^~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *^m.V=  
    7. 用Matlab画出照度数据 #rL@  
    8. 在Matlab计算照度平均值  0>J4O:k
