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。 Pgp`g.$<  
+ yF._Ie=  
配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: sPod)w?e  
enableservice('AutomationServer', true) GqT 0SP  
enableservice('AutomationServer') Oz: J8l%  
\j$q';9p  
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。 s?g`ufF.t  
VYj*LiR  
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: `BA,_N|6  
1. 在FRED脚本编辑界面找到参考. jwe^(U  
2. 找到Matlab Automation Server Type Library n=+K$R  
3. 将名字改为MLAPP k ='c*`IE

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。 {}W9m)I

现在将脚本代码公布如下,此脚本执行如下几个步骤: |1@/gqa  
1. 创建Matlab服务器。 < SIe5" {  
2. 移动探测面对于前一聚焦面的位置。 Z^ e?V7q  
3. 在探测面追迹光线 VX`E7Sf!}  
4. 在探测面计算照度 D@]*{WO  
5. 使用PutWorkspaceData发送照度数据到Matlab ,vnHEY&  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _W3>Km-A=/  
7. 用Matlab画出照度数据 $<~o,e-4  
8. 在Matlab计算照度平均值 #:5vN-9?  
9. 返回数据到FRED中 r/32pY
