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。 ('q vYQ  
\%Rta$ O?S  
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: KR(} A"  
enableservice('AutomationServer', true) gQ[^gPWP"  
enableservice('AutomationServer') 9[{>JRm.  
o`mIi  
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。 m%c0#=D

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: Df~p 'N-$  
1. 在FRED脚本编辑界面找到参考. 1`]IU_)1B  
2. 找到Matlab Automation Server Type Library |cGeL[  
3. 将名字改为MLAPP LDEW00zL

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。 :n9xH

现在将脚本代码公布如下,此脚本执行如下几个步骤: _*ou o<x  
1. 创建Matlab服务器。 M:Y*Tb6w  
2. 移动探测面对于前一聚焦面的位置。 PT#eXS9_  
3. 在探测面追迹光线 &s^>S? L-  
4. 在探测面计算照度 Dbdzb m7  
5. 使用PutWorkspaceData发送照度数据到Matlab (:-Jl"&R@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 aXbNDj ][  
7. 用Matlab画出照度数据 2\63&C^  
8. 在Matlab计算照度平均值 )s<WG}  
9. 返回数据到FRED中 3V Mh)
