[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。 O/Wc@Ln  
3UX})mW  
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： Mio~CJ"?  
enableservice('AutomationServer', true) S)\%.~ n  
enableservice('AutomationServer') $lrq*Nf9c  
}h)[>I(  
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。 ]hkway

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'r^v  
1. 在FRED脚本编辑界面找到参考. vN4g#,<  
2. 找到Matlab Automation Server Type Library f9 b=Zm'  
3. 将名字改为MLAPP wKAc ;!

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。 ^Ru/7pw5

1. 创建Matlab服务器。 ~FV Z0%+,  
2. 移动探测面对于前一聚焦面的位置。 bP 2IX  
3. 在探测面追迹光线 L~jKx)S%  
4. 在探测面计算照度 Ls^$E  
5. 使用PutWorkspaceData发送照度数据到Matlab ~?{"H<  
6. 使用PutFullMatrix发送标量场数据到Matlab中 cy6P=k*  
7. 用Matlab画出照度数据 ;-d :!*

9. 返回数据到FRED中 )rs);Pl
