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。 [Bpgb57En  
N4fuV?E`  
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:  }tv-  
enableservice('AutomationServer', true) f#JLE+0Y  
enableservice('AutomationServer') 9KXp0Q?-$  
4)'5;|pI  
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。 uaJ5'*

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: >PySd"u  
1. 在FRED脚本编辑界面找到参考. 30<dEoF  
2. 找到Matlab Automation Server Type Library yo (&~r  
3. 将名字改为MLAPP 'Q(A5zfN]Y

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。 Q `E{Oo,

现在将脚本代码公布如下,此脚本执行如下几个步骤: y62;&{?m  
1. 创建Matlab服务器。 L1rov  
2. 移动探测面对于前一聚焦面的位置。 6Mk@,\1  
3. 在探测面追迹光线 /~ V"v"7E  
4. 在探测面计算照度 g4Hq<W"  
5. 使用PutWorkspaceData发送照度数据到Matlab &]vd7Q.t  
6. 使用PutFullMatrix发送标量场数据到Matlab中 sU bZVPDr  
7. 用Matlab画出照度数据 'a"<uk3DT  
8. 在Matlab计算照度平均值 3\D jV2t  
9. 返回数据到FRED中 T_Y6AII
