[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。 :]"V-1#}  
IgzQr>  
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： YR70BOxK  
enableservice('AutomationServer', true) [ )F<V!  
enableservice('AutomationServer') 5(2;|I,T  
h;Qk@F  
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。 7=uj2.J6  
DDZ@$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： q)GdD==  
1. 在FRED脚本编辑界面找到参考. ^Pf WG*  
2. 找到Matlab Automation Server Type Library m~|40)   
3. 将名字改为MLAPP RFGff

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。 @W<m4fi

现在将脚本代码公布如下，此脚本执行如下几个步骤： u +hX  
1. 创建Matlab服务器。 o-\[,}T)M  
2. 移动探测面对于前一聚焦面的位置。 Ef\-VKh  
3. 在探测面追迹光线 $qiya[&G4  
4. 在探测面计算照度 _`V'r#Qn  
5. 使用PutWorkspaceData发送照度数据到Matlab U:`Kss`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~u{uZ(~
  
7. 用Matlab画出照度数据 zA 3_Lx!  
8. 在Matlab计算照度平均值 1 zZlC#V  
9. 返回数据到FRED中 9$t(&z=
