FRED案例-FRED如何调用Matlab

48,Aq*JFw  
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。 ;:xOW$  
il^SGH  
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: ),`MAevp  
enableservice('AutomationServer', true) 3$f%{~3  
    enableservice('AutomationServer') 5wXe^G  
7kpCBLM(}  
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。 1lRqjnzve&  
N{n}]Js1D-  
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: Yh/-6wg  
1. 在FRED脚本编辑界面找到参考. E\!:MCL  
2. 找到Matlab Automation Server Type Library KLBV(`MS  
    3. 将名字改为MLAPP  /bA\O   
     _@D}2  
     lh`inAt)"  
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。 kfb+OE:7

现在将脚本代码公布如下,此脚本执行如下几个步骤: J{72%S  
1. 创建Matlab服务器。 'R6D+Vk/  
2. 移动探测面对于前一聚焦面的位置。 Y+N^_2@+C  
3. 在探测面追迹光线 ;cZ9C 1  
4. 在探测面计算照度 CaNZScnZ  
5. 使用PutWorkspaceData发送照度数据到Matlab AEkgm^t.{  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |7WzTz  
7. 用Matlab画出照度数据 J)(H-xvV  
8. 在Matlab计算照度平均值 ko!38BH`/  
9. 返回数据到FRED中 S |T:rc(~
