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。 wQbN5*82  
0vOt. LC/S  
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: [ fvip_Pt  
enableservice('AutomationServer', true) to{/@^ D  
enableservice('AutomationServer') "S#4  
os6p1"_\f  
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。 m8'B7|s

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: e=K2]Y Q{  
1. 在FRED脚本编辑界面找到参考. XOgl> 1O  
2. 找到Matlab Automation Server Type Library $ZX^JWq  
3. 将名字改为MLAPP zy\p,  
;d$PQi  
#v!(uuq,  
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。 ^2Sa_.

现在将脚本代码公布如下,此脚本执行如下几个步骤: 59K%bz5t  
1. 创建Matlab服务器。 :K&>  
2. 移动探测面对于前一聚焦面的位置。 xxxM  
3. 在探测面追迹光线 ]-h$CJSY  
4. 在探测面计算照度 }YUUCq&  
5. 使用PutWorkspaceData发送照度数据到Matlab Zwy8 SD'L  
6. 使用PutFullMatrix发送标量场数据到Matlab中 U:6 J~  
7. 用Matlab画出照度数据 sute%6yM  
8. 在Matlab计算照度平均值 @y:mj \J9  
9. 返回数据到FRED中 3`sM/BoA
