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。 W4,'?o  
Sn0kJIb }  
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: ):[}NDmC  
enableservice('AutomationServer', true) ! 1=*"H%t  
enableservice('AutomationServer') 0'HQ=pP  
ap8q`a{j^  
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。 v[2&0&!K#

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: =P%&]5ts  
1. 在FRED脚本编辑界面找到参考. 51u\am'T  
2. 找到Matlab Automation Server Type Library +4  h!;i  
3. 将名字改为MLAPP Ia< V\$#

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。 $}.+}'7$

现在将脚本代码公布如下,此脚本执行如下几个步骤: M\/hK2J# #  
1. 创建Matlab服务器。 `/Rqt+C  
2. 移动探测面对于前一聚焦面的位置。 <:Mz2Rg  
3. 在探测面追迹光线 $C sE[+k1  
4. 在探测面计算照度 O5aXa_A_u  
5. 使用PutWorkspaceData发送照度数据到Matlab NYr)=&)Ke.  
6. 使用PutFullMatrix发送标量场数据到Matlab中 KzP{bK5/  
7. 用Matlab画出照度数据 >[Wjzg  
8. 在Matlab计算照度平均值 uorX;yekC  
9. 返回数据到FRED中 }W'4(V;:
