    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。 [-&Zl(9&  
    B<-Wea  
    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: u:EiwRW  
    enableservice('AutomationServer', true) ^Dx&|UwiZa  
        enableservice('AutomationServer') z{>Rc"%\  
    p[cX O=  
    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 Pz^544\~ou  
    I:.s_8mH}  
    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: EK'!}OGCG  
    1. 在FRED脚本编辑界面找到参考. Ss`LLq0LO  
    2. 找到Matlab Automation Server Type Library I@3MO0V^  
        3. 将名字改为MLAPP ite~E5?#  
         28nFRr  
         G&dKY h\  
    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。 W9)&!&<o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: gFh*eCo   
    1. 创建Matlab服务器。 &wX]_:?  
    2. 移动探测面对于前一聚焦面的位置。  3CJwj  
    3. 在探测面追迹光线 nP$9CA  
    4. 在探测面计算照度 ZB{EmB0W  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~5g~;f[4  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 H>C=zo,oiC  
    7. 用Matlab画出照度数据 ])!*_  
    8. 在Matlab计算照度平均值 o(HbGHIP  
    9. 返回数据到FRED中 P*o9a
