[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。 ;S=e%:zb  
]eL~L_[G\  
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： cFxSDTR  
enableservice('AutomationServer', true) B2"+Hwbk  
enableservice('AutomationServer') Oi#k:vq4  
c$.T<r)Z  
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。 A3!2"}L

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： ~l4Q~'  
1. 在FRED脚本编辑界面找到参考. <v-92?  
2. 找到Matlab Automation Server Type Library A'(k Yc  
3. 将名字改为MLAPP X)FQ%(H<

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。 otZ JY)

3. 在探测面追迹光线 wf^cyCR0  
4. 在探测面计算照度 ?##y`.+O  
5. 使用PutWorkspaceData发送照度数据到Matlab aGe\.A=  
6. 使用PutFullMatrix发送标量场数据到Matlab中 QTJrJD  
7. 用Matlab画出照度数据 vV2o[\o^  
8. 在Matlab计算照度平均值 [kQ"6wh8  
9. 返回数据到FRED中 y& Gw.N}<r
