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。 j&6,%s-M`a  
2E33m*C2  
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: 9z$]hl  
enableservice('AutomationServer', true) IEfzu L<v  
enableservice('AutomationServer') CC0@RU  
5Q#;4  
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。 =Mzg={)v  
OL4I}^*,  
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: +dX1`%RR[  
1. 在FRED脚本编辑界面找到参考. Dd-;;Y1C  
2. 找到Matlab Automation Server Type Library HJhPd#xCW  
3. 将名字改为MLAPP QM\v ruTB  
Y9Q-<~\z

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。 4EQ7OGU

现在将脚本代码公布如下,此脚本执行如下几个步骤: bE#=\kf|  
1. 创建Matlab服务器。 g]EDL<b  
2. 移动探测面对于前一聚焦面的位置。 T]Gxf"mK  
3. 在探测面追迹光线 KE1S5Mck>  
4. 在探测面计算照度 9uV/G7Geq  
5. 使用PutWorkspaceData发送照度数据到Matlab 3 $ cDC8  
6. 使用PutFullMatrix发送标量场数据到Matlab中 %Koc^ pb)  
7. 用Matlab画出照度数据 )IPnSh/ <  
8. 在Matlab计算照度平均值 r5jiB L~  
9. 返回数据到FRED中 {_0Efc=7
