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。 a(|0 '^  
i"Hc(lg  
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: lTN^c?  
enableservice('AutomationServer', true) 3LJ\y  
enableservice('AutomationServer') x $[_Hix  
+\dKe[j{g  
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。 :5&UWL|  
^jb;4nf  
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: \ kY:|T  
1. 在FRED脚本编辑界面找到参考. (nBh6u*  
2. 找到Matlab Automation Server Type Library Uc ,..  
3. 将名字改为MLAPP FqGMHM\J

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。 m~W[,7NE0&

现在将脚本代码公布如下,此脚本执行如下几个步骤: l_9ZzN  
1. 创建Matlab服务器。 VK,{Mu=.9  
2. 移动探测面对于前一聚焦面的位置。 3m4 sh~  
3. 在探测面追迹光线 `HYj:4v'  
4. 在探测面计算照度 .q:6F*,1M  
5. 使用PutWorkspaceData发送照度数据到Matlab ,Csjb1  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _*{Lha  
7. 用Matlab画出照度数据 8'qlg|{!~  
8. 在Matlab计算照度平均值 9&Y|,&W  
9. 返回数据到FRED中 Z-_Xt^N
