[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。 kSqMI'89  
*edhJUT  
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： \avgXndI  
enableservice('AutomationServer', true) pTcN8E&Unz  
enableservice('AutomationServer') \4hB1-
 
:W}M$5|  
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。 /80RO:'7

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： 1NU@k6UHl  
1. 在FRED脚本编辑界面找到参考. }C{wGK+o[  
2. 找到Matlab Automation Server Type Library 7,D6RP(b  
3. 将名字改为MLAPP

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。 ujoJ6UOG

1. 创建Matlab服务器。 k9oLJ<.k  
2. 移动探测面对于前一聚焦面的位置。 :J;*]o:  
3. 在探测面追迹光线 =7%c*O <  
4. 在探测面计算照度 Xp_G9I,+  
5. 使用PutWorkspaceData发送照度数据到Matlab LLW\1 cxi  
6. 使用PutFullMatrix发送标量场数据到Matlab中 t8z=R6zX  
7. 用Matlab画出照度数据 L=-v>YL+  
8. 在Matlab计算照度平均值 $n9Bp'<  
9. 返回数据到FRED中 `RLn)a
