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。 &x4*YM h  
iG"1~/U  
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: jw/@]f;N  
enableservice('AutomationServer', true) [.$/o}  
enableservice('AutomationServer') nITkgN:s  
'R#MH  
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。 K.Cx 9

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: gt=@v())  
1. 在FRED脚本编辑界面找到参考. twt's,dO  
2. 找到Matlab Automation Server Type Library 1uEM;O  
3. 将名字改为MLAPP p _2Yc]8  
z uo:yaO  
b/tc D r  
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。 j'Gezx^.<e

现在将脚本代码公布如下,此脚本执行如下几个步骤: Ci[Ja#p7$h  
1. 创建Matlab服务器。 HIvSh6|0p  
2. 移动探测面对于前一聚焦面的位置。 e:.D^G Fi  
3. 在探测面追迹光线 07\]8^/G  
4. 在探测面计算照度 =tX"aCW~  
5. 使用PutWorkspaceData发送照度数据到Matlab f1B t6|W%  
6. 使用PutFullMatrix发送标量场数据到Matlab中 B->oTC`5  
7. 用Matlab画出照度数据 {@'#|]4y.  
8. 在Matlab计算照度平均值 cnDF`7xrT  
9. 返回数据到FRED中 A6xN6{R!
