[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。 m>

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： 3:Aw.-,i\  
enableservice('AutomationServer', true) HH>"J/;c,  
enableservice('AutomationServer') ~Qzb<^9]  
sh []OSM
 
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。 ;2||g8'

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： HS{a^c%  
1. 在FRED脚本编辑界面找到参考. bkQEfx.  
2. 找到Matlab Automation Server Type Library b[Z5:[@\#  
3. 将名字改为MLAPP =HT:p:S

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。

1. 创建Matlab服务器。 XeD9RMT  
2. 移动探测面对于前一聚焦面的位置。 \\80c65-  
3. 在探测面追迹光线 k}-@N;zq  
4. 在探测面计算照度 ! 6kLL  
5. 使用PutWorkspaceData发送照度数据到Matlab 7\sJ=*  
6. 使用PutFullMatrix发送标量场数据到Matlab中 t:tT Zh  
7. 用Matlab画出照度数据 t?NB#/#%x  
8. 在Matlab计算照度平均值 _qg)^M6  
9. 返回数据到FRED中 !xs.[&u8
