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。 5p-vSWr !  
%,@e- &>  
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: bP|-GCKM8  
enableservice('AutomationServer', true) jaVx9FR +  
enableservice('AutomationServer') o)CW7Y#?,  
Uxe]T  
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。 :RYYjmG5;

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: vfVF^ WOd  
1. 在FRED脚本编辑界面找到参考. kFT*So`'  
2. 找到Matlab Automation Server Type Library VG$%Vs  
3. 将名字改为MLAPP nJ1<8 p

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。 X 3XTB*

现在将脚本代码公布如下,此脚本执行如下几个步骤: p^p1{%=  
1. 创建Matlab服务器。 Xg;<?g?k  
2. 移动探测面对于前一聚焦面的位置。 gF;C% }  
3. 在探测面追迹光线 )U0I|dx  
4. 在探测面计算照度 Y9%zo~]-W'  
5. 使用PutWorkspaceData发送照度数据到Matlab =NPo<^Lae  
6. 使用PutFullMatrix发送标量场数据到Matlab中 o?3C-A|  
7. 用Matlab画出照度数据 D*_. 4I  
8. 在Matlab计算照度平均值 {n<1uh9~$8  
9. 返回数据到FRED中  3L4v@
