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。 0MQ= Rt  
&{iC:zp  
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: fSh5u/F!  
enableservice('AutomationServer', true) GnV0~?  
enableservice('AutomationServer')  idmU.`  
8 WP>u8&  
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。 >&L|oq7$

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: > =>/~dIb  
1. 在FRED脚本编辑界面找到参考. BT_]=\zi  
2. 找到Matlab Automation Server Type Library fJ,N.O+9E  
3. 将名字改为MLAPP N&8TG  
KuNLu31%  
r^9l/H~ $  
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。 g14*6O:

现在将脚本代码公布如下,此脚本执行如下几个步骤: >nSsbhAe  
1. 创建Matlab服务器。 KaIKb=4L|  
2. 移动探测面对于前一聚焦面的位置。 UuG%5 ZC  
3. 在探测面追迹光线  a+h$u  
4. 在探测面计算照度 wNONh`b  
5. 使用PutWorkspaceData发送照度数据到Matlab }v1wpv/b(  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ;!yK~OBxt  
7. 用Matlab画出照度数据 337.' |ZE  
8. 在Matlab计算照度平均值 P -m_],  
9. 返回数据到FRED中 rK~-Wzwu
