[技术]FRED如何调用Matlab [复制链接]

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。 *1>Tc,mb  
Ag1nxV1M$  
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： :X*uE^bH  
enableservice('AutomationServer', true) 1'B=JyR~K  
enableservice('AutomationServer') eMH\]A~v"  
15DlD`QV  
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。 )*o) iN 7l

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： 0nlh0u8#  
1. 在FRED脚本编辑界面找到参考. tfe'].uT  
2. 找到Matlab Automation Server Type Library x_H"<-By  
3. 将名字改为MLAPP O9p^P%U"

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。 V<REcII.

现在将脚本代码公布如下，此脚本执行如下几个步骤： wKz*)C  
1. 创建Matlab服务器。 qv/chD`C  
2. 移动探测面对于前一聚焦面的位置。 r1$x}I#Zv  
3. 在探测面追迹光线 #mO.[IuD  
4. 在探测面计算照度 x1:1Jj:  
5. 使用PutWorkspaceData发送照度数据到Matlab ^}GR!990  
6. 使用PutFullMatrix发送标量场数据到Matlab中 %,)Xi  
7. 用Matlab画出照度数据 Mz6|#P}.s  
8. 在Matlab计算照度平均值 lt}U,p,S  
9. 返回数据到FRED中 u #7AB>wi{
