[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。 6+>q1,<

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： ,oR}0(^"\<  
enableservice('AutomationServer', true) 3*
ZE``  
enableservice('AutomationServer') yB&s2J  
8[eH8m#~$  
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。 '/mwX

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： #=h~Lr'UH  
1. 在FRED脚本编辑界面找到参考. z.FO6y6L  
2. 找到Matlab Automation Server Type Library )

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。 qWdL|8

1. 创建Matlab服务器。 074)(X&:x  
2. 移动探测面对于前一聚焦面的位置。 cZi/bIh  
3. 在探测面追迹光线 n"*A.  
4. 在探测面计算照度 JS}iNS'X  
5. 使用PutWorkspaceData发送照度数据到Matlab *1|&uE&_R  
6. 使用PutFullMatrix发送标量场数据到Matlab中 d=`hFwD9  
7. 用Matlab画出照度数据 ;BsyN[bF  
8. 在Matlab计算照度平均值 w

9. 返回数据到FRED中 UH2fP G
