[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。 ;&b%Se@#p

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： ya -i^i\  
enableservice('AutomationServer', true) ==H$zmK  
enableservice('AutomationServer') 2`a q**}  
1mSaS4!"B  
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。 8CC/BOe

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： $>R(W=Q  
1. 在FRED脚本编辑界面找到参考. Kv{8iAB#c  
2. 找到Matlab Automation Server Type Library -/D|]qqHm  
3. 将名字改为MLAPP rxO2js

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。  ?W0(|9

3. 在探测面追迹光线 m~],nl  
4. 在探测面计算照度 Q0{z).&\(e  
5. 使用PutWorkspaceData发送照度数据到Matlab #)`A7 $/,  
6. 使用PutFullMatrix发送标量场数据到Matlab中 =/+#PVO  
7. 用Matlab画出照度数据 ~"!a9GZ
