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。 4oF8F)ASj  
[8VB"{{&  
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~lE]Q3c7  
enableservice('AutomationServer', true) _:,:U[@Vz  
enableservice('AutomationServer') [kyF|3k~  
hoc$aqP6pp  
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。 0.~Pzg

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: 1>"K<6b+  
1. 在FRED脚本编辑界面找到参考. \wxS~T<&L  
2. 找到Matlab Automation Server Type Library T>&d/$;]  
3. 将名字改为MLAPP - T,;Fr'

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。 TvE M{

现在将脚本代码公布如下,此脚本执行如下几个步骤: T<|B1jA  
1. 创建Matlab服务器。 2z7+@!w/  
2. 移动探测面对于前一聚焦面的位置。 /3! KfG  
3. 在探测面追迹光线 ey@]B5  
4. 在探测面计算照度 M%dXy^e  
5. 使用PutWorkspaceData发送照度数据到Matlab 5'/Ney9N  
6. 使用PutFullMatrix发送标量场数据到Matlab中 SSKn7`  
7. 用Matlab画出照度数据 Uj)~>V'  
8. 在Matlab计算照度平均值 x.CNDG  
9. 返回数据到FRED中 ec: ?Q0
