[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。 "M*\,IH  
L'6zs:i  
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： =Tj0dfO|"  
enableservice('AutomationServer', true) -J6}7>4^8}  
enableservice('AutomationServer') 0+H"$2/  
eX$Biv1N  
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。 F%|(pHk

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： HYY|)Wo  
1. 在FRED脚本编辑界面找到参考. {M$8V~8D  
2. 找到Matlab Automation Server Type Library 6RtpB\hq  
3. 将名字改为MLAPP /;>EyWW

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。 }$UFc1He\J

1. 创建Matlab服务器。 ~& l`"

3. 在探测面追迹光线 j?,$*Fi  
4. 在探测面计算照度 bd9c/>&  
5. 使用PutWorkspaceData发送照度数据到Matlab <*\J 6:^n  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $200?[  
7. 用Matlab画出照度数据 _96&P7
