[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。 T)MKhK9\Ab  
G@s rQum(  
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： U`z=!KI+g  
enableservice('AutomationServer', true) /C}u,dBf  
enableservice('AutomationServer') eot%Th?[  
 _->d41  
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。 .r4*?>

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： 0l;TZf=H  
1. 在FRED脚本编辑界面找到参考. kZ$2Uss  
2. 找到Matlab Automation Server Type Library >4 VN1^  
3. 将名字改为MLAPP Qu|H_<8g

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。 7v't# =

现在将脚本代码公布如下，此脚本执行如下几个步骤： lha)4d  
1. 创建Matlab服务器。 7H.3.j(L  
2. 移动探测面对于前一聚焦面的位置。 e>0gE`8A  
3. 在探测面追迹光线

4. 在探测面计算照度 41g "7Mk  
5. 使用PutWorkspaceData发送照度数据到Matlab Z-:T')#Cf  
6. 使用PutFullMatrix发送标量场数据到Matlab中 "zj[v1K9-A  
7. 用Matlab画出照度数据 V_zU?}lZ^  
8. 在Matlab计算照度平均值 s@zO`uBc  
9. 返回数据到FRED中 Uo?4o*}
