FRED如何调用Matlab

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。 r"\<+$ 7  
kb~ 9/)~g  
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: l^$U~OB8k  
enableservice('AutomationServer', true) F#qc#s  
enableservice('AutomationServer') FEBRUk6.h  
oB '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。 !!Yf>0u#

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: ^nQJo"g\  
1. 在FRED脚本编辑界面找到参考. )]m4FC:  
2. 找到Matlab Automation Server Type Library [RTo[-ci2  
3. 将名字改为MLAPP m}6>F0Kv

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。 1WY$Vs

现在将脚本代码公布如下,此脚本执行如下几个步骤: =2} bQW  
1. 创建Matlab服务器。 9R&.$5[W(s  
2. 移动探测面对于前一聚焦面的位置。 PX?^v8wlqL  
3. 在探测面追迹光线 !yKrA|w1  
4. 在探测面计算照度 8|\xU9VT  
5. 使用PutWorkspaceData发送照度数据到Matlab .l,NmF9  
6. 使用PutFullMatrix发送标量场数据到Matlab中 a@?ebCE  
7. 用Matlab画出照度数据 ER4#5gd  
8. 在Matlab计算照度平均值 M?['HoRo  
9. 返回数据到FRED中 9G6auk.m.O
