yl3iU:+V 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。
y4envjl0 0BVMLRB 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:
l<qxr.X enableservice('AutomationServer', true)
Rmd;ug9 enableservice('AutomationServer')
!-\*rdE{9
nGyY`wt&Rg 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。
]vu'+F$ OjZ+gl} 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:
?rHc%H 1. 在FRED脚本编辑界面找到参考.
!})+WSs'"s 2. 找到Matlab Automation Server Type Library
]HCt%5 3. 将名字改为MLAPP
x28Bz*O x{ZcF=4
NU_VUd2 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。

|/r@z[t jP}N^ LY^BkH' 现在将脚本代码公布如下,此脚本执行如下几个步骤:
I98wMV8 1. 创建Matlab服务器。
EzthRe9 2. 移动探测面对于前一聚焦面的位置。
u` 3. 在探测面追迹
光线 `D GO~RMp9 4. 在探测面计算
照度 *4.f*3* 5. 使用PutWorkspaceData发送照度数据到Matlab
,~G[\2~p 6. 使用PutFullMatrix发送标量场数据到Matlab中
\>jK\j 7. 用Matlab画出照度数据
rg\|-_.es' 8. 在Matlab计算照度平均值
vmmu[v 9. 返回数据到FRED中
