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。 )Ln".Bu,  
Wj^e)2%  
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: o zn&>k  
enableservice('AutomationServer', true) cbyzZ#WRb  
enableservice('AutomationServer') \H:T)EVy  
v;e8W9M  
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。 I:iMRvp

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: W6i{ yne W  
1. 在FRED脚本编辑界面找到参考. KH;~VR8"/  
2. 找到Matlab Automation Server Type Library E3O^Tg?j  
3. 将名字改为MLAPP ) yMrE T m

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。 T8z?_ *k

现在将脚本代码公布如下,此脚本执行如下几个步骤: 8^ f:-5  
1. 创建Matlab服务器。 {m>ylE  
2. 移动探测面对于前一聚焦面的位置。 ;C$+8%P4  
3. 在探测面追迹光线 Mz6(M,hkq  
4. 在探测面计算照度 D1xGUz2r  
5. 使用PutWorkspaceData发送照度数据到Matlab Yw3'9m^  
6. 使用PutFullMatrix发送标量场数据到Matlab中 &R<aRE:+R  
7. 用Matlab画出照度数据 K'r;#I|"J  
8. 在Matlab计算照度平均值 1]2]l*&3  
9. 返回数据到FRED中 -  /\qGI
