-lhIL}mGf 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。
Iw`tbN
L[ o1ZVEvp 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:
09-8Xzz enableservice('AutomationServer', true)
|Gf<Ql_.4 enableservice('AutomationServer')
<{kPa_`'
>J7slDRo 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。
}ssV"5M YRlf U5 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:
B-MS@<2 1. 在FRED脚本编辑界面找到参考.
&u2;S?7m 2. 找到Matlab Automation Server Type Library
$H@SXx 3. 将名字改为MLAPP
7\6g>4J^` tn5%zJ#+ Kz"3ba}KH 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。
z$?F^3> 图 编辑/参考
Mk}T ]%Eh" ^aSb~lce 现在将脚本代码公布如下,此脚本执行如下几个步骤:
xJCxzJ 1. 创建Matlab服务器。
kkq1:\pZ]a 2. 移动探测面对于前一聚焦面的位置。
`j>5W<5q\ 3. 在探测面追迹
光线 c*)T4n[e 4. 在探测面计算
照度 MT-Tt 5. 使用PutWorkspaceData发送照度数据到Matlab
L]kBY2c 6. 使用PutFullMatrix发送标量场数据到Matlab中
*D?_,s 7. 用Matlab画出照度数据
k_7m[o 8. 在Matlab计算照度平均值
^O_Z5NbC3 9. 返回数据到FRED中
