    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。 bW^{I,b<F  
    (/_w23rr  
    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: 94[8~_{fG  
    enableservice('AutomationServer', true) Uee$5a>(  
        enableservice('AutomationServer') 19\ V@d^  
    8;(3fSNC  
    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 #\3X;{  
    6lQP+! EF  
    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: 9%?a\#C  
    1. 在FRED脚本编辑界面找到参考. DC'L-]#<  
    2. 找到Matlab Automation Server Type Library e1R<+`]  
        3. 将名字改为MLAPP LH 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。 42PA?^xPw

    2. 移动探测面对于前一聚焦面的位置。 lnrs4s Km  
    3. 在探测面追迹光线 Y\9zjewc  
    4. 在探测面计算照度 )!=X?fz,O  
    5. 使用PutWorkspaceData发送照度数据到Matlab p $,ZYF~  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 G;^,T/q47  
    7. 用Matlab画出照度数据  ]l=iKl  
    8. 在Matlab计算照度平均值 :i o[9B [
