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。 0d.lF:  
(r:WG!I,  
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: b- %7@j  
enableservice('AutomationServer', true) k&@JF@_TI  
enableservice('AutomationServer') H=7dp%b"  
`7+?1 z  
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。 4Uz6*IQNl

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: @v@'8E Q  
1. 在FRED脚本编辑界面找到参考. $ 'HiNP {c  
2. 找到Matlab Automation Server Type Library &)<]AG.vd!  
3. 将名字改为MLAPP P?\rRB  
$Pl>T09d  
Wf>UI)^n  
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。 7ugmZO}lL

现在将脚本代码公布如下,此脚本执行如下几个步骤: A~O 'l&KB  
1. 创建Matlab服务器。 bbS'ZkB\  
2. 移动探测面对于前一聚焦面的位置。 K)@]vw/\  
3. 在探测面追迹光线 kax9RH vku  
4. 在探测面计算照度 Oj~k1+*  
5. 使用PutWorkspaceData发送照度数据到Matlab R+rHa#M_  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?Q:se  
7. 用Matlab画出照度数据 d ID] {  
8. 在Matlab计算照度平均值 u;1#eP\;  
9. 返回数据到FRED中 `hI1
