[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。 |J-tU)|1vl  
]9<H[5>$R  
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： Vl(id_~_  
enableservice('AutomationServer', true) S"+#=C
 
enableservice('AutomationServer') '&|%^9O/"  
Rc@lGq9  
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。 L`:V]p  
/a$Zzs&xs  
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： .ezko\nU  
1. 在FRED脚本编辑界面找到参考. N1>M<N03  
2. 找到Matlab Automation Server Type Library HA$7Q~{N-t  
3. 将名字改为MLAPP otdv;xI9

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。 FAGi`X<L

现在将脚本代码公布如下，此脚本执行如下几个步骤： |e+r~).4B  
1. 创建Matlab服务器。 {poTA+i  
2. 移动探测面对于前一聚焦面的位置。 !}eq~3  
3. 在探测面追迹光线 vl`St$$|  
4. 在探测面计算照度 'w;J)_Yc2  
5. 使用PutWorkspaceData发送照度数据到Matlab VzM (u_)  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~2NTXp  
7. 用Matlab画出照度数据 'o8,XBv-  
8. 在Matlab计算照度平均值 /HSg
)  
9. 返回数据到FRED中 \u/=?b
