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。 ><DE1tG  
j"dbl?og  
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: 7)]G"m{  
enableservice('AutomationServer', true) 9(I4x]`  
enableservice('AutomationServer') FPMW"~v  
& 3a+6!L[  
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。 %$}iM<

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: ]Lh\[@#1f  
1. 在FRED脚本编辑界面找到参考. 8_ LDS  
2. 找到Matlab Automation Server Type Library >ylVES/V  
3. 将名字改为MLAPP \E30.>%,

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。 5Tu.2.)N

现在将脚本代码公布如下,此脚本执行如下几个步骤: ~+g5?y  
1. 创建Matlab服务器。 8 , =$>@u  
2. 移动探测面对于前一聚焦面的位置。 -Z@ p   
3. 在探测面追迹光线 'SY &-<t(  
4. 在探测面计算照度 yqU++;6  
5. 使用PutWorkspaceData发送照度数据到Matlab i>~?XVU  
6. 使用PutFullMatrix发送标量场数据到Matlab中 6 qq7:  
7. 用Matlab画出照度数据 3m^BYr*y^  
8. 在Matlab计算照度平均值  96BMJE'  
9. 返回数据到FRED中 MoA{ /{
