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。 h 1:uTrtA  
% Lhpj[C  
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: Z;P[)q  
enableservice('AutomationServer', true) -yy&q9  
enableservice('AutomationServer') -:h5Ky"  
"[q/2vC  
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。 O&!+ni  
&&\ h%-Jc  
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: <=l!~~%  
1. 在FRED脚本编辑界面找到参考. U"v(9m@  
2. 找到Matlab Automation Server Type Library ><mZOTn e;  
3. 将名字改为MLAPP H 0aDWFWS

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。 vQ#$.*Cvn

现在将脚本代码公布如下,此脚本执行如下几个步骤: 3k` "%R.H  
1. 创建Matlab服务器。 ~}q"M[{  
2. 移动探测面对于前一聚焦面的位置。 mT <4@RrB  
3. 在探测面追迹光线 R]VY PNns  
4. 在探测面计算照度 v`A^6)U#M  
5. 使用PutWorkspaceData发送照度数据到Matlab TR L4r_  
6. 使用PutFullMatrix发送标量场数据到Matlab中 UTGR{>=>  
7. 用Matlab画出照度数据 {a.{x+!5I-  
8. 在Matlab计算照度平均值 j#S>8: G  
9. 返回数据到FRED中 uc<XdFcu
