[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。 6azGhxh  
v6M6>&RR|  
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： M4oy  
enableservice('AutomationServer', true) Vvn
2 Ep  
enableservice('AutomationServer') JPc+rfF  
0y" $MC v  
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。 0KcyLAJ

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： P}y +G|  
1. 在FRED脚本编辑界面找到参考. 9Zt`u,;  
2. 找到Matlab Automation Server Type Library RXpw!  
3. 将名字改为MLAPP \K{0L

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。 7$vYo _

1. 创建Matlab服务器。 B:;pvW]  
2. 移动探测面对于前一聚焦面的位置。 U0 Yll4E  
3. 在探测面追迹光线 b8`)y<7  
4. 在探测面计算照度 3s,g*  
5. 使用PutWorkspaceData发送照度数据到Matlab xd q?/^E  
6. 使用PutFullMatrix发送标量场数据到Matlab中 +j`5F3@  
7. 用Matlab画出照度数据 av}k)ZT_  
8. 在Matlab计算照度平均值 @;zl  
9. 返回数据到FRED中 q#Z@+(^
