[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。 I}awembw g  
;h#Q!M&e#  
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： +hs:W'`%  
enableservice('AutomationServer', true) dd4^4X`j  
enableservice('AutomationServer') 'a~F'FN$  

Ol;"}3*Z*  
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。 ,,?XGx

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： ~b[5}_L=>  
1. 在FRED脚本编辑界面找到参考. D8b9T.[(  
2. 找到Matlab Automation Server Type Library 1b@]^Ue  
3. 将名字改为MLAPP xg;F};}5$

K'[kl'  
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。 >B.KI}dE

现在将脚本代码公布如下，此脚本执行如下几个步骤： $6d5W=u$H  
1. 创建Matlab服务器。 BNixp[Hc  
2. 移动探测面对于前一聚焦面的位置。 qI[AsM+  
3. 在探测面追迹光线 ( ;KTV*1  
4. 在探测面计算照度 XFi9qL^  
5. 使用PutWorkspaceData发送照度数据到Matlab 2TQ<XHA\  
6. 使用PutFullMatrix发送标量场数据到Matlab中 LfvRH?<W  
7. 用Matlab画出照度数据 g c<Y?a-  
8. 在Matlab计算照度平均值 j(c;r>  
9. 返回数据到FRED中 hS^8/]E={
