    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。  1r$q $\  
    (fC [Y  
    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: 8@ b83  
    enableservice('AutomationServer', true) /IODRso/!  
    enableservice('AutomationServer') 6u7>S?  
    n<MH\.!tM  
    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 @#nB]qV:e  
    p\Jz<dkN1  
    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: YDP<  
    1. 在FRED脚本编辑界面找到参考. S>nM&758  
    2. 找到Matlab Automation Server Type Library LbnR=B!  
    3. 将名字改为MLAPP IL\#!|>

    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@ }Jd0D4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: F9N)UW:w  
    1. 创建Matlab服务器。 ZhW>H  
    2. 移动探测面对于前一聚焦面的位置。 _&P![o)x  
    3. 在探测面追迹光线 \59+JLmP4  
    4. 在探测面计算照度 v*kTTaU&  
    5. 使用PutWorkspaceData发送照度数据到Matlab 'F1NBL   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 't]=ps  
    7. 用Matlab画出照度数据 VUk2pEGO.  
    8. 在Matlab计算照度平均值 u9J;OsnHK  
    9. 返回数据到FRED中 +c?1\{M
