[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。 \ \gAa-}:  
vGchKN~_  
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： ,D\}DJ`)C  
enableservice('AutomationServer', true) A\|:hzu+  
enableservice('AutomationServer') &0SgEUZr  
W$:D#;jz`h  
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。 L | #"Yn

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： 76b2 3|  
1. 在FRED脚本编辑界面找到参考. wexa\o  
2. 找到Matlab Automation Server Type Library U9"Ij}  
3. 将名字改为MLAPP =4K:l}}

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。 `h<>_zpjY

现在将脚本代码公布如下，此脚本执行如下几个步骤： 7x.] 9J  
1. 创建Matlab服务器。 '3 JVUHn  
2. 移动探测面对于前一聚焦面的位置。 C@ "l"  
3. 在探测面追迹光线 /`g~lww2O  
4. 在探测面计算照度 g&X X@I8+v  
5. 使用PutWorkspaceData发送照度数据到Matlab )5w#n1  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8r48+_y3u  
7. 用Matlab画出照度数据 0xUn#&A~  
8. 在Matlab计算照度平均值 +5H1n(6)  
9. 返回数据到FRED中 Z._%T$8aJv
