Y#I8gzv 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。
K\KQ(N8F CVvl &on 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:
|JR`" nF` enableservice('AutomationServer', true)
bl&9O enableservice('AutomationServer')
+L"F] _?
b+q'xnA=> 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。
:!l.ze{F V dvj*I 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:
k~so+k&=b 1. 在FRED脚本编辑界面找到参考.
4CchE15 2. 找到Matlab Automation Server Type Library
Iila|,cM 3. 将名字改为MLAPP
MM]0}65KG [TQYu:e ovOV&Zt 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。
5L<A7^j 图 编辑/参考
x1Y/^ks@2 7FkiT 50|nQ:u, 现在将脚本代码公布如下,此脚本执行如下几个步骤:
OM^`P 1. 创建Matlab服务器。
p#Po? 2. 移动探测面对于前一聚焦面的位置。
c~/poFj 3. 在探测面追迹
光线 jbq x7x 4. 在探测面计算
照度 "=K3sk 5. 使用PutWorkspaceData发送照度数据到Matlab
A(uo%QE| 6. 使用PutFullMatrix发送标量场数据到Matlab中
=BN<)f^*s 7. 用Matlab画出照度数据
"=+i~N#Sc 8. 在Matlab计算照度平均值
JL!^R_b&c 9. 返回数据到FRED中
