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。 hAOXOj1

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: =gGK243  
enableservice('AutomationServer', true) :GIY"l'  
enableservice('AutomationServer') "ltvD\  
394u']M  
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。 37ll8

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: mppBc-#EYr  
1. 在FRED脚本编辑界面找到参考. CHdw>/5  
2. 找到Matlab Automation Server Type Library !}"npUgE  
3. 将名字改为MLAPP E;$t|~ #

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。 MCurKT<pQ

现在将脚本代码公布如下,此脚本执行如下几个步骤: vn .wM  
1. 创建Matlab服务器。 ' hO+b  
2. 移动探测面对于前一聚焦面的位置。 XZV)4=5iSO  
3. 在探测面追迹光线 5WO!u:!'  
4. 在探测面计算照度 "3Dvc7V  
5. 使用PutWorkspaceData发送照度数据到Matlab (dpBGt@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 <9"s&G@  
7. 用Matlab画出照度数据 ).9-=P HlX  
8. 在Matlab计算照度平均值 \Wt&z,  
9. 返回数据到FRED中 ;1NZY.pyc
