*z[G+JX 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。
88}+.-3t$
o&uO ] 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:
'f&o%5] enableservice('AutomationServer', true)
fm$eJu enableservice('AutomationServer')
r>73IpJI
K$OxeJP?F 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。
SY\ UuZ (ii6w d<* 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:
-
s[=$pDU 1. 在FRED脚本编辑界面找到参考.
:#D?b.= 2. 找到Matlab Automation Server Type Library
! |SPOk 3. 将名字改为MLAPP
T=r-6eN ~^d. zIN! iEx.BQ+ 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。

1. 创建Matlab服务器。
BiGB<Jr 2. 移动探测面对于前一聚焦面的位置。
~\= VSwJ 3. 在探测面追迹
光线 W>C!V 4. 在探测面计算
照度 \#4??@+Xf 5. 使用PutWorkspaceData发送照度数据到Matlab
l`lo5:w 6. 使用PutFullMatrix发送标量场数据到Matlab中
is=sV:j: 7. 用Matlab画出照度数据
zNSix!F 8. 在Matlab计算照度平均值
5
o:VixZf 9. 返回数据到FRED中
