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。 t} zffe-  
S0\;FmLIc  
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: UvSvgDMl  
enableservice('AutomationServer', true) K 9ytot  
enableservice('AutomationServer') TX96 ^EoH  
Gk9Y{  
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。 ^T[8j/9o^  
y\DR,$Py  
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: cuO)cj]@e  
1. 在FRED脚本编辑界面找到参考. bqHR~4 #IR  
2. 找到Matlab Automation Server Type Library i(^&ZmG  
3. 将名字改为MLAPP L7*,v5  
4LRrrW  
2F0@M|'  
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。 Une,Y4{u

现在将脚本代码公布如下,此脚本执行如下几个步骤: M^c`j#NQ  
1. 创建Matlab服务器。 e`pYO]Z  
2. 移动探测面对于前一聚焦面的位置。 |g vx^)ro  
3. 在探测面追迹光线 }Fd4; ]  
4. 在探测面计算照度 y9cDPwi:b  
5. 使用PutWorkspaceData发送照度数据到Matlab !o+Y" * /  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Bb 5|+b P  
7. 用Matlab画出照度数据 )[d?&GK  
8. 在Matlab计算照度平均值 l^ P[nQDH  
9. 返回数据到FRED中 (!72Eaw:]
