&7 YTz3aj 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。
dSkW[r9Z%l kq
SpZoV0' 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:
/ ao|v enableservice('AutomationServer', true)
dt -=7mz# enableservice('AutomationServer')
; SS/bS|
uP-I7l0i1 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。
vncak =wEqI)Td 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:
GYX/G>-r 1. 在FRED脚本编辑界面找到参考.
P)2.Gx/ 2. 找到Matlab Automation Server Type Library
#]iSh(|8 3. 将名字改为MLAPP
.FarKW R*l#[D5A fR&;E 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。

{*Ag[HS0u nNCG*Vu 9\_^"5l 现在将脚本代码公布如下,此脚本执行如下几个步骤:
sUc_) 1. 创建Matlab服务器。
L*Gk1' 2. 移动探测面对于前一聚焦面的位置。
yl>V' 3. 在探测面追迹
光线 V!Px975P 4. 在探测面计算
照度 4@b~)av) 5. 使用PutWorkspaceData发送照度数据到Matlab
Z#O )0ou 6. 使用PutFullMatrix发送标量场数据到Matlab中
b"lzR[X,e 7. 用Matlab画出照度数据
}=dUASL 8. 在Matlab计算照度平均值
M@k8;_5 9. 返回数据到FRED中
