84&XW 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。
gY9\o#)< W$?e<@ 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:
`3iQZui enableservice('AutomationServer', true)
:wgfW .w enableservice('AutomationServer')
$;D*
n'8Fx
eK`PxoTI-I 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。
O%1/r* +3^NaY`Y 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:
Q1tpCT 1. 在FRED脚本编辑界面找到参考.
}C(5 -7 2. 找到Matlab Automation Server Type Library
h
; kfh. 3. 将名字改为MLAPP
s\0K o1 m s~8QL :mv`\ 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。

MC=G "m:_ 1. 创建Matlab服务器。
!0fI"3P@r 2. 移动探测面对于前一聚焦面的位置。
jQtSwVDr 3. 在探测面追迹
光线 0rzVy/Z( 4. 在探测面计算
照度 yBn_Kd 5. 使用PutWorkspaceData发送照度数据到Matlab
v:d9o.h 6. 使用PutFullMatrix发送标量场数据到Matlab中
T{S4|G1R6 7. 用Matlab画出照度数据
m@oUvxcd 8. 在Matlab计算照度平均值
?y-s20Kd 9. 返回数据到FRED中
