[分享]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。 x,'!eCKN  
`He,p -  
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： fj&i63?e  
enableservice('AutomationServer', true) (P`3 @H  
enableservice('AutomationServer') N 8-oY$*  
@$z<i `4  
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。 M %Qt|@O  
gmm.{%1_I;  
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： y a_<^O 9  
1. 在FRED脚本编辑界面找到参考. nWHa.H#  
2. 找到Matlab Automation Server Type Library T'~!9Q  
3. 将名字改为MLAPP n..g~$k

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。 %!1Q P[}K

现在将脚本代码公布如下，此脚本执行如下几个步骤： x]33LQ1]  
1. 创建Matlab服务器。 kTvd+TP4  
2. 移动探测面对于前一聚焦面的位置。 x@Hc@R<!  
3. 在探测面追迹光线 3@]SKfoo1  
4. 在探测面计算照度 LWt&3  
5. 使用PutWorkspaceData发送照度数据到Matlab &ZQJ>#~j^  
6. 使用PutFullMatrix发送标量场数据到Matlab中
L/z),#  
7. 用Matlab画出照度数据 .e3+s*  
8. 在Matlab计算照度平均值 .AU)*7Gh  
9. 返回数据到FRED中 2j&AiD
