    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。 y3 {'s>O6  
    HQJ_:x 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: 5ltEnvN  
    enableservice('AutomationServer', true) T2<?4^xN  
    enableservice('AutomationServer') IL;JdIa  
    Z0uo. H@.N  
    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 M!Q27wT8 O  
    <E/4/ ANN  
    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: Ezsb'cUa(  
    1. 在FRED脚本编辑界面找到参考. >-J%=P  
    2. 找到Matlab Automation Server Type Library R?MRRq  
    3. 将名字改为MLAPP _uwM%M;  
    wCw-EGLR  
    }%Mj`Bh  
    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。 -< D7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: < %@e<,8  
    1. 创建Matlab服务器。 Wi7!J[ B  
    2. 移动探测面对于前一聚焦面的位置。 ZeM~13[  
    3. 在探测面追迹光线 HYU-F_|N=  
    4. 在探测面计算照度 zG-pqE6  
    5. 使用PutWorkspaceData发送照度数据到Matlab & \tD$g~"  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 9<0TF+}>  
    7. 用Matlab画出照度数据 `#@#e Z  
    8. 在Matlab计算照度平均值 s8BfOl-  
    9. 返回数据到FRED中 zwJB.4@
