/c=8$y\%@ 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。
ZrEou}z(* ]I,&Bme 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:
cI8\d 4/py enableservice('AutomationServer', true)
8Gy]nD enableservice('AutomationServer')
P?>:YY53
0qFO+nC 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。
Ne|CWUhO A]0R?N9wb_ 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:
Zj]tiN f\" 1. 在FRED脚本编辑界面找到参考.
u3 LoP_| 2. 找到Matlab Automation Server Type Library
`;}qjm0a 3. 将名字改为MLAPP
S;Sy.Lp 4K:Aqqhds GOdWc9Ta! 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。

/'DAB** h='&^1 &&<l}E 现在将脚本代码公布如下,此脚本执行如下几个步骤:
;U?=YSHk7 1. 创建Matlab服务器。
wS|k3^OV% 2. 移动探测面对于前一聚焦面的位置。
&?QKWxN 3. 在探测面追迹
光线 sYXLVJ>b 4. 在探测面计算
照度 E.m2- P;4 5. 使用PutWorkspaceData发送照度数据到Matlab
THOYx :Nr; 6. 使用PutFullMatrix发送标量场数据到Matlab中
OjffN'a+N 7. 用Matlab画出照度数据
\Kui`X 8. 在Matlab计算照度平均值
_X?_|!;J 9. 返回数据到FRED中
