    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。 XzIx:J6  
    KvFMs\o6p  
    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: k?GD/$1t  
    enableservice('AutomationServer', true) 5 `D-  
    enableservice('AutomationServer') ]e?x# <S  
    Y"g.IK`V  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 !^c@shLN4  
     l! bv^  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ]b?9zeT*'l  
    1. 在FRED脚本编辑界面找到参考. )RgGcHT@  
    2. 找到Matlab Automation Server Type Library s@4nWe  
    3. 将名字改为MLAPP @@G6p($

    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*%#o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |KI UgI  
    1. 创建Matlab服务器。 HvwYm.$zE  
    2. 移动探测面对于前一聚焦面的位置。 )j l 8!O7  
    3. 在探测面追迹光线 J5Z%ImiT^O  
    4. 在探测面计算照度 zw<p74DH  
    5. 使用PutWorkspaceData发送照度数据到Matlab g]~h(mI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Uh eC  
    7. 用Matlab画出照度数据 )::>q5c  
    8. 在Matlab计算照度平均值 G6P)C##ibn  
    9. 返回数据到FRED中 @oP_;G
