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。 :acnrW>i[@  
OE)n4X  
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: dd1m~Gm  
enableservice('AutomationServer', true) 3|zqEGT*  
enableservice('AutomationServer') 6Ug( J$Ouh  
{o"X8  
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。 EeGP E

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: .|Y2'TWQ  
1. 在FRED脚本编辑界面找到参考. >!O3 jb k  
2. 找到Matlab Automation Server Type Library # D"TY-$.=  
3. 将名字改为MLAPP |S48xsFvq  
p48M7OV  
F{}mlQg  
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。 #- $?2?2

现在将脚本代码公布如下,此脚本执行如下几个步骤: ~$XbYR-  
1. 创建Matlab服务器。 m qgA  
2. 移动探测面对于前一聚焦面的位置。 f`'?2  
3. 在探测面追迹光线 fkE4 [X7f  
4. 在探测面计算照度 ~qQSt%  
5. 使用PutWorkspaceData发送照度数据到Matlab edld(/wu~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 *(6vO{  
7. 用Matlab画出照度数据 ETvn$ Jdp  
8. 在Matlab计算照度平均值 c:etJ  
9. 返回数据到FRED中  jL8[;*^G
