%llG/]q# 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。
XZhhr1-<a ; ?!sU 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:
\2Yh I0skW enableservice('AutomationServer', true)
=$MV3] enableservice('AutomationServer')
piU4%EO
?S"xR0 * 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
V%))%?3x_ ctf'/IZ5 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
<iMLM<J<w 1. 在FRED脚本编辑界面找到参考.
D3eK!'qS 2. 找到Matlab Automation Server Type Library
!*p lK6a 3. 将名字改为MLAPP
~/t#J bz1\EkLL K|iNEhuc 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。
<R2bz1!h. 图 编辑/参考
^pn:SV Ab2VF;z : 5QlJX 现在将脚本代码公布如下,此脚本执行如下几个步骤:
FkH4|}1 1. 创建Matlab服务器。
GFvOrRlP\ 2. 移动探测面对于前一聚焦面的位置。
7Ev~yY;N 3. 在探测面追迹
光线 Q,>AT$| 4. 在探测面计算
照度 7JbN WN 5. 使用PutWorkspaceData发送照度数据到Matlab
Xh?{%?2 6. 使用PutFullMatrix发送标量场数据到Matlab中
mV-MJ$3r 7. 用Matlab画出照度数据
74Lq!e3hMF 8. 在Matlab计算照度平均值
56fcifXz@ 9. 返回数据到FRED中
