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。 D +oo5  
?oF@q :W  
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: S !e0 :  
enableservice('AutomationServer', true)  $SDx) '!  
enableservice('AutomationServer') ="4jk=on  
z4<h)hh"k6  
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。 kfHLjr.  
(O&b:D/Y  
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: QR#,n@fE  
1. 在FRED脚本编辑界面找到参考. E6US  
2. 找到Matlab Automation Server Type Library @3G3l|~>  
3. 将名字改为MLAPP N0XGW_f  
kn<[v;+  
J|>P,x#G  
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。 +yTL

现在将脚本代码公布如下,此脚本执行如下几个步骤: C2VZE~U+  
1. 创建Matlab服务器。 #(A>yW702  
2. 移动探测面对于前一聚焦面的位置。 4f1*?HX&  
3. 在探测面追迹光线 aJfW75C  
4. 在探测面计算照度 -V+fQGZe  
5. 使用PutWorkspaceData发送照度数据到Matlab [~;9Mi.XL  
6. 使用PutFullMatrix发送标量场数据到Matlab中 rN*4Y  
7. 用Matlab画出照度数据 yb]a p  
8. 在Matlab计算照度平均值  [g/g(RL  
9. 返回数据到FRED中 xE}q(.]
