[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。 SVJL|S3k  
%MA o<,ha  
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： H<Ne\
zAv  
enableservice('AutomationServer', true) QQ*`tmy  
enableservice('AutomationServer') E.ugr])  
XBvJc'(s  
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。 /Qa'\X,f3

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： ~2HlAU))<&  
1. 在FRED脚本编辑界面找到参考. IjshxNk  
2. 找到Matlab Automation Server Type Library ?2RDd|#  
3. 将名字改为MLAPP &3@{?K

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。 Za"m;+H<E

3. 在探测面追迹光线 h?8I`Z)h  
4. 在探测面计算照度 nfj8z@!  
5. 使用PutWorkspaceData发送照度数据到Matlab d ynq)lf  
6. 使用PutFullMatrix发送标量场数据到Matlab中 `rWT^E@p5m  
7. 用Matlab画出照度数据 iJ-z&=dOe  
8. 在Matlab计算照度平均值 ekR/X  
9. 返回数据到FRED中 M/d6I$~7z
