[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。 |"\lL9CT  
*1v_6<;2i<  
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： Q9q9<J7j$  
enableservice('AutomationServer', true) mxhW|}_-j  
enableservice('AutomationServer') AeQC:  
/cY[at
|p  
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。 *NjMb{[ZQ  
i*A$SJ:}  
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： f#c BQ~  
1. 在FRED脚本编辑界面找到参考. Cha?7F[xL  
2. 找到Matlab Automation Server Type Library -faw:  
3. 将名字改为MLAPP [Ekgft&

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。 2dyxKK!\a

1. 创建Matlab服务器。 W7]mfy^  
2. 移动探测面对于前一聚焦面的位置。 dcR6KG8  
3. 在探测面追迹光线 3]7ipwF2q  
4. 在探测面计算照度 6(sfpK'  
5. 使用PutWorkspaceData发送照度数据到Matlab 2}@*Ki7  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ^CX,nj_(  
7. 用Matlab画出照度数据 /gF]s_
 
8. 在Matlab计算照度平均值 LA

9. 返回数据到FRED中 '[xut1{
