[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。 Ja^ 5?Ar|  
u3tZ[Y2 c  
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： ekf$dgoR  
enableservice('AutomationServer', true) x4a:PuqmGG  
enableservice('AutomationServer') VFD%h }  
|E/L.gdP7  
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。 zjX7C~h^Q

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： \Mx JH[  
1. 在FRED脚本编辑界面找到参考. zxZtz  
2. 找到Matlab Automation Server Type Library r;cV&T/?  
3. 将名字改为MLAPP Sj 3oV

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。 #'o7x'n^

1. 创建Matlab服务器。 GaNq2G  
2. 移动探测面对于前一聚焦面的位置。 ?H;{~n?  
3. 在探测面追迹光线 W5DbFSgB  
4. 在探测面计算照度 u"VS* hSH  
5. 使用PutWorkspaceData发送照度数据到Matlab uOk%AL>  
6. 使用PutFullMatrix发送标量场数据到Matlab中 FbSa~uN  
7. 用Matlab画出照度数据 1IA5.@G:  
8. 在Matlab计算照度平均值 d;suACW  
9. 返回数据到FRED中 /r$&]C:Fi
