[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。 y)N57#e  
V~p/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： 3n-~+2l  
enableservice('AutomationServer', true) :X7"fX  
enableservice('AutomationServer') !ckm
NE0  
- `^594  
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。 G/ToiUY  
S(xlN7=  
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： $,R QA^gxW  
1. 在FRED脚本编辑界面找到参考. h ,;f6  
2. 找到Matlab Automation Server Type Library #M$Gj>E%4  
3. 将名字改为MLAPP m":lKXpQ

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。 wRu+:<o^.

现在将脚本代码公布如下，此脚本执行如下几个步骤： z/zUb``  
1. 创建Matlab服务器。 rMkoE7n  
2. 移动探测面对于前一聚焦面的位置。 Bu4J8eLx  
3. 在探测面追迹光线 mD@#,B7A  
4. 在探测面计算照度 yxq+<A4,a  
5. 使用PutWorkspaceData发送照度数据到Matlab #;ezMRKM"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 /7Z5_q_  
7. 用Matlab画出照度数据 KICy! "af  
8. 在Matlab计算照度平均值 F!m/n!YR  
9. 返回数据到FRED中 LPr34BK
