[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。 H,D5)1Uu

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： Z66Xj-o  
enableservice('AutomationServer', true) |eRE'Wd0  
enableservice('AutomationServer') T={!/y+
 
/4+L2O[  
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。 #w''WOk@ZG

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： Z`kVyuQ  
1. 在FRED脚本编辑界面找到参考. @x1cV_s[  
2. 找到Matlab Automation Server Type Library 9,8/DW.K  
3. 将名字改为MLAPP kI"

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。 E]Mx<7;\.

1. 创建Matlab服务器。 iY>P7Uvvz  
2. 移动探测面对于前一聚焦面的位置。 * K$U[$s  
3. 在探测面追迹光线 |cd"cx+  
4. 在探测面计算照度 Yz;7g8HI  
5. 使用PutWorkspaceData发送照度数据到Matlab azFJ-0n@"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 w7`pbcY,  
7. 用Matlab画出照度数据 d%I7OBBx@
 
8. 在Matlab计算照度平均值 |[~S&  
9. 返回数据到FRED中 6Gg`ExcT5
