[分享]FRED如何调用Matlab [复制链接]

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。 .Jrqm  
Y))u&*RuT0  
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： r]l!WRn  
enableservice('AutomationServer', true) xgNJeQ  
enableservice('AutomationServer') L?Qg#YSd~  
]) rrG/3  
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。 '&gF>  
n;$5Cq!v=  
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： *WIj4G.d  
1. 在FRED脚本编辑界面找到参考. }f8Uc+  
2. 找到Matlab Automation Server Type Library J]G?Rc  
3. 将名字改为MLAPP A%D7bQ

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。 _-9@qe

现在将脚本代码公布如下，此脚本执行如下几个步骤： T:IW%?M  
1. 创建Matlab服务器。 1Lg-.-V  
2. 移动探测面对于前一聚焦面的位置。 B,K>rCZ/  
3. 在探测面追迹光线 ;zIP,PMM  
4. 在探测面计算照度 @Q^P{  
5. 使用PutWorkspaceData发送照度数据到Matlab USVqB\#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W0k0$\i
X  
7. 用Matlab画出照度数据

8. 在Matlab计算照度平均值 N^pJS6cJkl  
9. 返回数据到FRED中 :bWUuXVtJ
