[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。 DMf^>{[  
F,:F9r?l,H  
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： ^D.B^BR  
enableservice('AutomationServer', true) a$aI%  
enableservice('AutomationServer') {B\.8)&8  
gmLw.|-  
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。 [&{"1Z

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： `=-}S+  
1. 在FRED脚本编辑界面找到参考. X/7: *  
2. 找到Matlab Automation Server Type Library B.Xm*adBT  
3. 将名字改为MLAPP 2tWUBt\,g

Z@I%ppd  
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。 40g&zU-

1. 创建Matlab服务器。 aY {.  
2. 移动探测面对于前一聚焦面的位置。 2>EIDRLJ-  
3. 在探测面追迹光线 G&uj}rj  
4. 在探测面计算照度 yv'rJI~ Ps  
5. 使用PutWorkspaceData发送照度数据到Matlab vG\Wr.h0!=  
6. 使用PutFullMatrix发送标量场数据到Matlab中 )bK<t  
7. 用Matlab画出照度数据 p!Gf^  
8. 在Matlab计算照度平均值 $C[YqZO  
9. 返回数据到FRED中 qQ1m5_OD`z
