[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。 GIcq|Pe  
-s`Wd4AP  
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： 
q0Q[]|L  
enableservice('AutomationServer', true) R%\3
[  
enableservice('AutomationServer') 3Wbd=^hRvq  
U]vUa^nG  
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。 ?QJx!'Y,p

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： rg k1.0U0  
1. 在FRED脚本编辑界面找到参考. Sk!' 2y*@&  
2. 找到Matlab Automation Server Type Library ht]n*  
3. 将名字改为MLAPP L/-SWid)

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。 +pYwc0~

1. 创建Matlab服务器。 Fs $FR-x  
2. 移动探测面对于前一聚焦面的位置。 ]1d)jWG  
3. 在探测面追迹光线 { >izfG,\  
4. 在探测面计算照度 S|k@D2k=  
5. 使用PutWorkspaceData发送照度数据到Matlab P![ZO6`:W'  
6. 使用PutFullMatrix发送标量场数据到Matlab中 8~-TN1H  
7. 用Matlab画出照度数据 C

9. 返回数据到FRED中 _rIo @v
