q83~j`ZJ$ 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。
aoDD&JE PGPbpl&\t 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:
7_40_kwJi enableservice('AutomationServer', true)
cN WcNMm enableservice('AutomationServer')
`MsYgd
qX+gG",8 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。
As+;qNO +qUkMx 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:
2d2@ J{ 1. 在FRED脚本编辑界面找到参考.
Ww96|m 2. 找到Matlab Automation Server Type Library
akhL\-d)al 3. 将名字改为MLAPP
U>_IYT
o? i.v0@!K v0C;j(2zb 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。

照度 WY"Y)S 5. 使用PutWorkspaceData发送照度数据到Matlab
t@(9ga( 6. 使用PutFullMatrix发送标量场数据到Matlab中
l#b|@4:I 7. 用Matlab画出照度数据
MkDK/K$s 8. 在Matlab计算照度平均值
/c@*eU 9. 返回数据到FRED中
