    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。 b.O9ITR  
    3u>8\|8wz  
    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: L&-hXGx=7  
    enableservice('AutomationServer', true) y[@\j9Hq  
    enableservice('AutomationServer') ^+SkCO  
    ]0B|V2D#e  
    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 <?0~1o\Ur

    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: }<jb vCeK  
    1. 在FRED脚本编辑界面找到参考. NDO\B,7  
    2. 找到Matlab Automation Server Type Library I =Wc&1g  
    3. 将名字改为MLAPP OTB$V k

    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。 $XBAZ<"hd

    现在将脚本代码公布如下,此脚本执行如下几个步骤: x\s,= n3z  
    1. 创建Matlab服务器。 ?@6/Alk  
    2. 移动探测面对于前一聚焦面的位置。 QO{y/{  
    3. 在探测面追迹光线 Q 6C-4ja  
    4. 在探测面计算照度 r' BAT3  
    5. 使用PutWorkspaceData发送照度数据到Matlab ftk%EYT;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Wk4.%tpeO7  
    7. 用Matlab画出照度数据 ?R Fg$Z'^  
    8. 在Matlab计算照度平均值 qJR!$?  
    9. 返回数据到FRED中 kJs^ z
