[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。 A

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： i40'U?eG~6  
enableservice('AutomationServer', true) 3tt3:`g  
enableservice('AutomationServer') <-]qU}-  
Az`c? W%  
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。 ]T?Py)

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： mSg{0_:  
1. 在FRED脚本编辑界面找到参考. XK";-7TZt  
2. 找到Matlab Automation Server Type Library [f1'Qb  
3. 将名字改为MLAPP I*SrKZb

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。 \~r`2p-K

1. 创建Matlab服务器。 6w"_sK?  
2. 移动探测面对于前一聚焦面的位置。 !jySID?q  
3. 在探测面追迹光线 }%T8?d]  
4. 在探测面计算照度 ]SO-NR  
5. 使用PutWorkspaceData发送照度数据到Matlab '1 }ybSG  
6. 使用PutFullMatrix发送标量场数据到Matlab中 X%Lhu6F  
7. 用Matlab画出照度数据 z>6hK:27  
8. 在Matlab计算照度平均值 j6JK4{  
9. 返回数据到FRED中 pef)c,U$
