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。 QV)}3pW  
, ,{6m d  
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: Hs<n^fyf  
enableservice('AutomationServer', true) O|(o8 VS  
enableservice('AutomationServer') 7ti<  
8dV=1O$ /  
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。 oQBiPN+v.3  
!d|8'^gc  
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: -,@bA @&  
1. 在FRED脚本编辑界面找到参考. r03I*b  
2. 找到Matlab Automation Server Type Library M 5rwoyn  
3. 将名字改为MLAPP gN\*Y  
+QupM  
gL,"ef+nM  
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。 x?>!UqgkY

现在将脚本代码公布如下,此脚本执行如下几个步骤: 8v$ g  
1. 创建Matlab服务器。 s9:%s*$u  
2. 移动探测面对于前一聚焦面的位置。 Lkp&;+  
3. 在探测面追迹光线 wV %8v\  
4. 在探测面计算照度 g?$e^ls  
5. 使用PutWorkspaceData发送照度数据到Matlab sVlZNj9i"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 XL?A w  
7. 用Matlab画出照度数据 J2Y 3er  
8. 在Matlab计算照度平均值 iZu:uMoc  
9. 返回数据到FRED中 I-,Xwj-
