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。 ]]j^  
Fp\;j\pfw  
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: .psb# 4  
enableservice('AutomationServer', true) 1!z{{H;W  
enableservice('AutomationServer') @KQ>DBWQM  
'=dQ$fs  
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。 T^v763%  
sT^R0Q'>  
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: JK$3qUDnI  
1. 在FRED脚本编辑界面找到参考. 8$IKQNS  
2. 找到Matlab Automation Server Type Library jVff@)_S  
3. 将名字改为MLAPP 'f( CN3.!

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。 u)@:V)z

现在将脚本代码公布如下,此脚本执行如下几个步骤: #,#`< h!  
1. 创建Matlab服务器。 "OLg2O^  
2. 移动探测面对于前一聚焦面的位置。 xfRp_;l+R  
3. 在探测面追迹光线 +ktv : d  
4. 在探测面计算照度 &gCGc?/R#  
5. 使用PutWorkspaceData发送照度数据到Matlab D ,kxB~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 HE&)N clY  
7. 用Matlab画出照度数据 P@v"aa\@2)  
8. 在Matlab计算照度平均值 6 f*:;  
9. 返回数据到FRED中 x}/jh
