FRED如何调用Matlab

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。 y42 Cg  
:R=6Ku>  
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: #8"oqqYi  
enableservice('AutomationServer', true) "%Y=+  
enableservice('AutomationServer') +71<B>L   
Fy Ih\  
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。 0t^FM<7G

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: A8vd@0  
1. 在FRED脚本编辑界面找到参考. S\8v)|Pr  
2. 找到Matlab Automation Server Type Library iLuC_.'u=  
3. 将名字改为MLAPP HS{Vohy>  
IUv#nB3  
Vn sV&cx  
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。 Fb]+h)on

现在将脚本代码公布如下,此脚本执行如下几个步骤: f|q/2}Bqb  
1. 创建Matlab服务器。 %5gdLm!p  
2. 移动探测面对于前一聚焦面的位置。 j@z IJ  
3. 在探测面追迹光线 Mww^  
4. 在探测面计算照度 vnvpb! @Q  
5. 使用PutWorkspaceData发送照度数据到Matlab } jJKE  
6. 使用PutFullMatrix发送标量场数据到Matlab中 l EFd^@t  
7. 用Matlab画出照度数据 ]5f;Kz)  
8. 在Matlab计算照度平均值 R#4l"  
9. 返回数据到FRED中 ?yef?JI$p
