[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。 1e Wl:S}

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： AOh\%|}  
enableservice('AutomationServer', true) PS*=MyNa  
enableservice('AutomationServer') 2(_+PQ6C=  
\ C^fi}/]  
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。 ~;m3i3D

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： +`;YK7o  
1. 在FRED脚本编辑界面找到参考.

2. 找到Matlab Automation Server Type Library !/1a

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。 }N^A (`L

1. 创建Matlab服务器。 f-w-K)y$ht  
2. 移动探测面对于前一聚焦面的位置。 `WjRb  
3. 在探测面追迹光线 s-\.j-Sa  
4. 在探测面计算照度 4#pn]  
5. 使用PutWorkspaceData发送照度数据到Matlab z#$>f*b  
6. 使用PutFullMatrix发送标量场数据到Matlab中 %Tc P[<  
7. 用Matlab画出照度数据 B%~hVpm,eM  
8. 在Matlab计算照度平均值 x.=Np\#\G-  
9. 返回数据到FRED中 m)5,ut/
