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。 f -F}~S  
DW9MX`!Xc  
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: *w _o8!3-  
enableservice('AutomationServer', true) ~@l4T_,k  
enableservice('AutomationServer') V,Nu!$)J  
BgT ^  
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。 ] L#c <0  
j[A(@ w"  
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: 7 rRI-wZ  
1. 在FRED脚本编辑界面找到参考. D^m2iW;  
2. 找到Matlab Automation Server Type Library =Hd#"9-  
3. 将名字改为MLAPP ElB[k<  
FI?J8a  
d^6-P  R_  
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。 i6n,N)%H

现在将脚本代码公布如下,此脚本执行如下几个步骤: SZ[?2z  
1. 创建Matlab服务器。 %} zkmEY.e  
2. 移动探测面对于前一聚焦面的位置。 |k*bWuXgLs  
3. 在探测面追迹光线 .$}z</#!  
4. 在探测面计算照度 2/V%jS[4#y  
5. 使用PutWorkspaceData发送照度数据到Matlab 0wVM% Dng  
6. 使用PutFullMatrix发送标量场数据到Matlab中 y3 N[F  
7. 用Matlab画出照度数据 H.;}%id  
8. 在Matlab计算照度平均值 /"k[T  
9. 返回数据到FRED中 579D
