%Y7\0q~Z 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。
TmZ%
;TN {G:dhi 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:
UE2!,Z, enableservice('AutomationServer', true)
7$8YBcZ6 enableservice('AutomationServer')
Cy'0O>v5
WJp9io[GM 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。
1Y2]jz4 vN`2KCl~3 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:
K'6dlwn). 1. 在FRED脚本编辑界面找到参考.
E>t5/^c)*w 2. 找到Matlab Automation Server Type Library
!Nu ~4 3. 将名字改为MLAPP
RqV* O}Am -RisZ-n* HzcI2
P`| 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。

Qy>n]->% 2. 移动探测面对于前一聚焦面的位置。
jF5Y-CX 3. 在探测面追迹
光线 8T&.8r 4. 在探测面计算
照度 &LRO^[d 5. 使用PutWorkspaceData发送照度数据到Matlab
A4lW8&rHI 6. 使用PutFullMatrix发送标量场数据到Matlab中
'&XL|_Iq 7. 用Matlab画出照度数据
\e89 >m 8. 在Matlab计算照度平均值
:qfP>Ok 9. 返回数据到FRED中
