c`s ]ciC 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。
/oC@:7 .T*89cEu 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:
\J-}Dp\0b enableservice('AutomationServer', true)
u;Rm/. enableservice('AutomationServer')
AYHefAF<w
4NDT5sL 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。
#q9cjEd_7 !.cno& 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:
J/>9w 1. 在FRED脚本编辑界面找到参考.
Aq,&p,m03 2. 找到Matlab Automation Server Type Library
e\95X{_' 3. 将名字改为MLAPP
W8N__ ]&_z@Z.i t2hI^J0y 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。

C+vk9:" /D,<2>o $TY1'#1U; 现在将脚本代码公布如下,此脚本执行如下几个步骤:
H$!sK 1. 创建Matlab服务器。
7*(K%e"U 2. 移动探测面对于前一聚焦面的位置。
z|v/hUrD 3. 在探测面追迹
光线 xz*MFoE 4. 在探测面计算
照度 /|WBk} 5. 使用PutWorkspaceData发送照度数据到Matlab
\:Z8"~G 6. 使用PutFullMatrix发送标量场数据到Matlab中
s0/y> ok 7. 用Matlab画出照度数据
v<:/u(i 8. 在Matlab计算照度平均值
HSlAm&Y\ 9. 返回数据到FRED中
