[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。 IJz=SV  
c u:1|gt  
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： ^;[|,:8f7L  
enableservice('AutomationServer', true) F
9\T<  
enableservice('AutomationServer') B
!X;T9^d  
}}4u>1,~  
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。 )~CnDk}^R

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： uhJnDo  
1. 在FRED脚本编辑界面找到参考. YKtF)N;m]  
2. 找到Matlab Automation Server Type Library [Kc"L+H\  
3. 将名字改为MLAPP ,y%4QvG7a

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。 -YD+xPD

1. 创建Matlab服务器。 sH_5.+,`  
2. 移动探测面对于前一聚焦面的位置。 $wq[W,'#L  
3. 在探测面追迹光线 08 $y1;  
4. 在探测面计算照度 Sh(Ws2b7  
5. 使用PutWorkspaceData发送照度数据到Matlab LLlt9(^d  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _RI!Z   
7. 用Matlab画出照度数据 yR|Beno  
8. 在Matlab计算照度平均值 riuG,$

9. 返回数据到FRED中 Rx\.x? &
