[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。 %OJ"@6A  
]FNe&o1zX  
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： c( _R xLJ  
enableservice('AutomationServer', true) ffW-R)U|3  
enableservice('AutomationServer') V=gu'~  
g& ou[_A  
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。 63`5A3rii

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： U(+%iD60i  
1. 在FRED脚本编辑界面找到参考. '2qbIYanh  
2. 找到Matlab Automation Server Type Library r}:Dg fn  
3. 将名字改为MLAPP ! FVD_8

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。 ep6V2R

现在将脚本代码公布如下，此脚本执行如下几个步骤： ww

1. 创建Matlab服务器。 !5qV}5  
2. 移动探测面对于前一聚焦面的位置。 O]XgA0]  
3. 在探测面追迹光线 tUksIUYD\  
4. 在探测面计算照度 s"`Oj5  
5. 使用PutWorkspaceData发送照度数据到Matlab _'|C-j`u$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 C1#f/o->  
7. 用Matlab画出照度数据 DaBy<pGb?  
8. 在Matlab计算照度平均值 4d_Az'7`4  
9. 返回数据到FRED中 HXN. ,[
