    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。 "YdEE\  
    J_Ltuso  
    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: kn)t'_jC  
    enableservice('AutomationServer', true) :1t~[-h^  
    enableservice('AutomationServer') Q#h 9n]5  
    Xc"&0v%;#  
    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 |#1(Z-}  
    C2Xd?d  
    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: k+I}PuG  
    1. 在FRED脚本编辑界面找到参考. FOq1>>a0  
    2. 找到Matlab Automation Server Type Library `wF8k{Pb  
    3. 将名字改为MLAPP n,$IfC"  
    A)%A!

    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。 2I*;A5$N1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: zIP6\u  
    1. 创建Matlab服务器。 pv^O"Bs  
    2. 移动探测面对于前一聚焦面的位置。 '* \|; l#1  
    3. 在探测面追迹光线 "#(T  
    4. 在探测面计算照度 Hwo$tVa:=  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~QvqG{bFB  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 kP/M< X"  
    7. 用Matlab画出照度数据 6s0_#wZC  
    8. 在Matlab计算照度平均值 5M9 I,  
    9. 返回数据到FRED中 0b4R
