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。 ^oR qu  
@"H7Q1Hg!*  
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: y;_F[m  
enableservice('AutomationServer', true) sRZ?Ilua6  
enableservice('AutomationServer') g_0| `Sm  
AR{$P6u!%|  
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。 IC1nR u2I

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: ZQn>+c2%!  
1. 在FRED脚本编辑界面找到参考. FAX[| p  
2. 找到Matlab Automation Server Type Library eZD"!AT  
3. 将名字改为MLAPP FL4BdJ\  
Hp5.F>-  
CR;E*I${  
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。 Nw(hN+_u

现在将脚本代码公布如下,此脚本执行如下几个步骤: 4iZg2"[D  
1. 创建Matlab服务器。 ?9>wG7cps7  
2. 移动探测面对于前一聚焦面的位置。 {&L^|X  
3. 在探测面追迹光线 )l/ .<`|  
4. 在探测面计算照度 %Y"pVBc  
5. 使用PutWorkspaceData发送照度数据到Matlab $zF%F.rln  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ]{|lGtK %  
7. 用Matlab画出照度数据 #,97 ]  
8. 在Matlab计算照度平均值 KW3<5+w]c  
9. 返回数据到FRED中 u /DE
