[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。 {zri6P+s  
}3Mnq?.-  
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： BwpSw\\?@  
enableservice('AutomationServer', true) ;ye5HlH}.  
enableservice('AutomationServer') y>5??q  
3O'6 Ae  
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。 S%sD#0l  
T=kR!Gx  
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： T08SGB]  
1. 在FRED脚本编辑界面找到参考. v{T%`WuPRf  
2. 找到Matlab Automation Server Type Library FthrI  
3. 将名字改为MLAPP |@+/R .l

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。 z"vI

3. 在探测面追迹光线 +'@j~\>^yJ  
4. 在探测面计算照度 mbS`+)1=l  
5. 使用PutWorkspaceData发送照度数据到Matlab ]'[(MH"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 CHojF+e  
7. 用Matlab画出照度数据 `> :^c  
8. 在Matlab计算照度平均值 sb3k? q  
9. 返回数据到FRED中 ,?k~>,{3
