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。 +4N7 _Y  
iE~][_%U  
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: s?:&#  
enableservice('AutomationServer', true) oV(|51(f  
enableservice('AutomationServer') -/y]'_a  
cL]vJ`?Ih  
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。 '\ MYC8"  
_:B/XZ  
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: /Vg=+FEO  
1. 在FRED脚本编辑界面找到参考. ZCT\4Llv#  
2. 找到Matlab Automation Server Type Library <K(qv^C  
3. 将名字改为MLAPP 7O=N78M  
C V{kP8#

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。 O7M8!3Eqm

现在将脚本代码公布如下,此脚本执行如下几个步骤: e;*GbXd|  
1. 创建Matlab服务器。 >{seaihK  
2. 移动探测面对于前一聚焦面的位置。 [eWZ^Eh"I  
3. 在探测面追迹光线 )2tDX=D  
4. 在探测面计算照度 ]tjQy1M  
5. 使用PutWorkspaceData发送照度数据到Matlab T uk:: .jD  
6. 使用PutFullMatrix发送标量场数据到Matlab中 z f rEM  
7. 用Matlab画出照度数据 9_h  V1:  
8. 在Matlab计算照度平均值 K~C6dy  
9. 返回数据到FRED中 hyHeyDO2
