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。 t,;b*ZR  
Q_a%$a.rV  
配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: Iyvl6  
enableservice('AutomationServer', true) :Ee5:S   
enableservice('AutomationServer') [ \Aor[(  
Va'K~$d_  
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。 Th*mm3D6

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 @X 6  
1. 在FRED脚本编辑界面找到参考. ?)5M3 lV3k  
2. 找到Matlab Automation Server Type Library /h%MWCZWm^  
3. 将名字改为MLAPP *'(dcy9  
S[M\com'  
Jh:-<xy)  
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。 !PrO~

现在将脚本代码公布如下,此脚本执行如下几个步骤: `+/[0B=.  
1. 创建Matlab服务器。 VbX$i!>8  
2. 移动探测面对于前一聚焦面的位置。 P6 G/J-  
3. 在探测面追迹光线 u]c nbm  
4. 在探测面计算照度 G8?<(.pi@  
5. 使用PutWorkspaceData发送照度数据到Matlab f1>^kl3@P  
6. 使用PutFullMatrix发送标量场数据到Matlab中 V1;Qt-i  
7. 用Matlab画出照度数据 Y<.F/iaH  
8. 在Matlab计算照度平均值 i]LK,'  
9. 返回数据到FRED中 ?8 C+wW
