[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。 Q)H1

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： r=`]L-}V  
enableservice('AutomationServer', true) W{{{c2.  
enableservice('AutomationServer') ]xYm@%>6  
NY& |
:F  
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。 Gp PlO]

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： 5W(S~}  
1. 在FRED脚本编辑界面找到参考. WN_i-A1G/h  
2. 找到Matlab Automation Server Type Library _i-

3. 将名字改为MLAPP E>|xv#:~DV

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?,6;%xB

1. 创建Matlab服务器。 b')Lj]%;k  
2. 移动探测面对于前一聚焦面的位置。 H=f'nm]dQ  
3. 在探测面追迹光线 U'Xw'?Uj  
4. 在探测面计算照度 rl<!h5  
5. 使用PutWorkspaceData发送照度数据到Matlab 7n_'2qY  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ub#>kCL9  
7. 用Matlab画出照度数据 HLPnbI-+  
8. 在Matlab计算照度平均值 IO(Y_7  
9. 返回数据到FRED中 E@f2hW2
