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。 LW_ Y  
$>'}6?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: )ZzwD]  
enableservice('AutomationServer', true) F<BhN+U  
enableservice('AutomationServer') ;w4rwL  
O8SX#,3^}  
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。 ^*C6]*C}te

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: V5KAiG<d  
1. 在FRED脚本编辑界面找到参考. xp/u, q  
2. 找到Matlab Automation Server Type Library H:U1#bQQ:  
3. 将名字改为MLAPP v3S{dX<  
Wr`=P,  
l,h#RTfry  
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。 n$y1kD

现在将脚本代码公布如下,此脚本执行如下几个步骤: r!Eo8C  
1. 创建Matlab服务器。 @U;-5KYYi  
2. 移动探测面对于前一聚焦面的位置。 F"hi2@/TI  
3. 在探测面追迹光线 St|sUtj<r  
4. 在探测面计算照度 {0QD-b o  
5. 使用PutWorkspaceData发送照度数据到Matlab N<Bi.\XC  
6. 使用PutFullMatrix发送标量场数据到Matlab中 g%j z,|  
7. 用Matlab画出照度数据 po=*%Zs*T  
8. 在Matlab计算照度平均值 wVE"nN#  
9. 返回数据到FRED中 ZeWHSU
