[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。 TQjM3Ri=V

s7~:VQ  
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： A]WR-0Z7  
enableservice('AutomationServer', true) u&7c2|Q  
enableservice('AutomationServer') _go1gf7  
{Bd 0  
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。 9[7Gxmf

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： {rE]y C^  
1. 在FRED脚本编辑界面找到参考. E5EA

2. 找到Matlab Automation Server Type Library 017(I:V?(:  
3. 将名字改为MLAPP O&(@Ka

x*}*0).  
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。 l^"HcP6

1. 创建Matlab服务器。 =yy7P[D  
2. 移动探测面对于前一聚焦面的位置。 }0(.HMiGj  
3. 在探测面追迹光线 hiM nU  
4. 在探测面计算照度 N-Jp; D  
5. 使用PutWorkspaceData发送照度数据到Matlab lgL|[ik`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 q=+AN</  
7. 用Matlab画出照度数据 l^,"^vz  
8. 在Matlab计算照度平均值 fkjo  
9. 返回数据到FRED中 8F#z)>q~
