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。 #:_Kws>+  
;JT-kw6l5K  
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: Bk c4TO  
enableservice('AutomationServer', true) YkSl^j[DHs  
enableservice('AutomationServer') t{9GVLZ  
nR~@#P\  
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。 ;igIZ$&

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: F/{!tx  
1. 在FRED脚本编辑界面找到参考. 'H>^2C iM  
2. 找到Matlab Automation Server Type Library rs[T=CQ  
3. 将名字改为MLAPP ? OM!+O  
%sP*=5?vA

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。  <kqo^

现在将脚本代码公布如下,此脚本执行如下几个步骤: FVKTbvYn  
1. 创建Matlab服务器。 + &Eqk  
2. 移动探测面对于前一聚焦面的位置。 gr2U6gi  
3. 在探测面追迹光线 &p@O _0nF  
4. 在探测面计算照度 ZLejcYS  
5. 使用PutWorkspaceData发送照度数据到Matlab #c!lS<z  
6. 使用PutFullMatrix发送标量场数据到Matlab中 M%m4i9~!?  
7. 用Matlab画出照度数据 g3y~bf  
8. 在Matlab计算照度平均值 TD0 B%  
9. 返回数据到FRED中 =dKtV.L
