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。 &2.DZ),L  
gREk,4DAv  
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: ^uG^>Om*  
enableservice('AutomationServer', true) i/C% 1<  
enableservice('AutomationServer') (#6Fg|f4Y  
nVoWER:  
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。 yMyvX_UNI

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: 9 iJ$M!  
1. 在FRED脚本编辑界面找到参考. "~.4z,ha  
2. 找到Matlab Automation Server Type Library ZXo;E  
3. 将名字改为MLAPP "doiD=b  
CvZ\Z472.j  
a {x3FQ  
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。 6~jAh@-

现在将脚本代码公布如下,此脚本执行如下几个步骤: i?b9zn  
1. 创建Matlab服务器。 qs\Cwn!  
2. 移动探测面对于前一聚焦面的位置。 $nW9VMa  
3. 在探测面追迹光线 2[(~_VJ  
4. 在探测面计算照度 IUEpE9_  
5. 使用PutWorkspaceData发送照度数据到Matlab 1MO-60  
6. 使用PutFullMatrix发送标量场数据到Matlab中 j `!Ge  
7. 用Matlab画出照度数据 7BINqVS&  
8. 在Matlab计算照度平均值 co\Il]`R/  
9. 返回数据到FRED中 dG0zA D
