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。 E2nsBP=5C  
<Pnz$nH:e  
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: AY(z9 &;6  
enableservice('AutomationServer', true) 6OPYq*|  
enableservice('AutomationServer') VpO+52&  
E9bc pup  
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。 sX c|++  
K2o\+t  
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: _!ITCkBj  
1. 在FRED脚本编辑界面找到参考. S|Yz5)*  
2. 找到Matlab Automation Server Type Library tb1w 6jaU  
3. 将名字改为MLAPP vU9j|z  
+ e3{J_  
DkA@KS1Dq  
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。 xm*6I

现在将脚本代码公布如下,此脚本执行如下几个步骤: =U`9_]~1c@  
1. 创建Matlab服务器。 (Do](C  
2. 移动探测面对于前一聚焦面的位置。 ?.~hex#M@  
3. 在探测面追迹光线 GE!fh1[[u  
4. 在探测面计算照度 "Nh}_jO  
5. 使用PutWorkspaceData发送照度数据到Matlab 7Ap==J{a  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Q13>z%Rge  
7. 用Matlab画出照度数据 [rO TWN  
8. 在Matlab计算照度平均值 A>Y#-e;<d  
9. 返回数据到FRED中 _qp^+
