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。 G l+[ |?N  
>W"gr]R<  
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: <@FOqi{o{  
enableservice('AutomationServer', true) W=M`Bkw{  
enableservice('AutomationServer') O"4Q=~Y  
)/H=m7}1h  
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。 _[-+%RP

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: ((A]FOIbO  
1. 在FRED脚本编辑界面找到参考. 5uMh#dm^  
2. 找到Matlab Automation Server Type Library X3#/|>  
3. 将名字改为MLAPP H8~<;6W

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。 zyTP|SXk

现在将脚本代码公布如下,此脚本执行如下几个步骤: +MPM^m  
1. 创建Matlab服务器。 Q[^IX  
2. 移动探测面对于前一聚焦面的位置。 7 Xe|P1@)  
3. 在探测面追迹光线 b7g\wnV8z  
4. 在探测面计算照度 kM5N#|!  
5. 使用PutWorkspaceData发送照度数据到Matlab XnrOC|P$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~H/|J^ J  
7. 用Matlab画出照度数据 78>)<$+d  
8. 在Matlab计算照度平均值 c%v[p8 %
