    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。 (,|,j(=]  
    Rh=" <'d  
    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: 8g#$Y2P  
    enableservice('AutomationServer', true) iJs~NLCgVu  
    enableservice('AutomationServer') 1Bytu >2  
    (v]%kXy/G  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 _4S^'FDo  
     o E+'@  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: g4?2'G5m?  
    1. 在FRED脚本编辑界面找到参考. X~{6$J|]#i  
    2. 找到Matlab Automation Server Type Library CoN[Yf3\  
    3. 将名字改为MLAPP C=?S  
    Sn=6[RQ>P  
    MB]E[&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。 o_:v?Y>0

    1. 创建Matlab服务器。 }M07-qIX{  
    2. 移动探测面对于前一聚焦面的位置。 t@%w:*&  
    3. 在探测面追迹光线 i<uU_g'M  
    4. 在探测面计算照度 @6 he!wW  
    5. 使用PutWorkspaceData发送照度数据到Matlab V?mP7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v?8WQNy  
    7. 用Matlab画出照度数据 =EJ&=t  
    8. 在Matlab计算照度平均值 w-|Rb~XT h  
    9. 返回数据到FRED中 v\x l?F
