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。 3 c=kYcj  
5*pzL0,Y  
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: 56 3mz-  
enableservice('AutomationServer', true) FQDf?d5  
enableservice('AutomationServer') k2U*dn"9U  
,yYcjs!=o  
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。 uw}Rr7q  
O,Q.-  
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: D(AH3`*|#  
1. 在FRED脚本编辑界面找到参考. t;e&[eg  
2. 找到Matlab Automation Server Type Library Wh)D_  
3. 将名字改为MLAPP 5I622d

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。 Hc)z:x;Sj

现在将脚本代码公布如下,此脚本执行如下几个步骤: 4ba*Nc*Yc  
1. 创建Matlab服务器。 H3A$YkK [  
2. 移动探测面对于前一聚焦面的位置。 pM?;QG;jA  
3. 在探测面追迹光线 EhcJE;S)  
4. 在探测面计算照度 s^wm2/Yw  
5. 使用PutWorkspaceData发送照度数据到Matlab B*(]T|ff<  
6. 使用PutFullMatrix发送标量场数据到Matlab中 u,sR2&Fe  
7. 用Matlab画出照度数据 ~KBa-i%o  
8. 在Matlab计算照度平均值 <^5!]8*O  
9. 返回数据到FRED中 ?d7,0Ex P
