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。 e7qMt[.  
vqz#V=J{  
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: 6v O)s!b  
enableservice('AutomationServer', true) {}&f\6OI%  
enableservice('AutomationServer') EiP&Y,vT  
)h_ 7 2  
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。 [k 7N+W8

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: >@"3Q`  
1. 在FRED脚本编辑界面找到参考. 8!Mzr1:  
2. 找到Matlab Automation Server Type Library @<TZH  
3. 将名字改为MLAPP U{uWk3I_b

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。 cW\Y?x

现在将脚本代码公布如下,此脚本执行如下几个步骤: 5@t uo`k  
1. 创建Matlab服务器。 JKi@Kw  
2. 移动探测面对于前一聚焦面的位置。 9iddanQA  
3. 在探测面追迹光线 xc<eU`-' b  
4. 在探测面计算照度 gXLZ)>+A+  
5. 使用PutWorkspaceData发送照度数据到Matlab CSqb)\8Oi*  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~EWfEHf*BJ  
7. 用Matlab画出照度数据 V&j.>Y  
8. 在Matlab计算照度平均值 2G}7R5``9  
9. 返回数据到FRED中 D)ne *},
