[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。 7lY&/-V  
*,{. oO9#  
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： oQI3Yz  
enableservice('AutomationServer', true) \Xc6K!HJM  
enableservice('AutomationServer') 2;r(?ebw  
rcMVYSj0  
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。 %YG ~ql  
\ F#mwl,>"  
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： >w+WG0Z K  
1. 在FRED脚本编辑界面找到参考. 'm}K$h(U  
2. 找到Matlab Automation Server Type Library ^-cj=on=Q  
3. 将名字改为MLAPP \NKf$"x}

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。 G<OC99;8

1. 创建Matlab服务器。 q]YPDdR#  
2. 移动探测面对于前一聚焦面的位置。 N~_GJw@  
3. 在探测面追迹光线 !}|n3wQ  
4. 在探测面计算照度 `Gzuk

5. 使用PutWorkspaceData发送照度数据到Matlab F2]v]]F!  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $UavM|  
7. 用Matlab画出照度数据 `4__X;  
8. 在Matlab计算照度平均值 f1(V~{N,+  
9. 返回数据到FRED中 7tMV*{+Z
