6qFzo1LO 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。
@jm +TW M,@M5o2u 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:
W&)f#/M8 enableservice('AutomationServer', true)
q,L>PN+W enableservice('AutomationServer')
i0K 2#}=^
z+7V}aPM 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。
|ymW0gh7o$ Ig}hap]G 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:
H'zAMGZa 1. 在FRED脚本编辑界面找到参考.
W+1nf:AI. 2. 找到Matlab Automation Server Type Library
H=C~h\me? 3. 将名字改为MLAPP
l`zhKj <<u]WsW{C iL);bv W 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。

5. 使用PutWorkspaceData发送照度数据到Matlab
Es7
c2YdU 6. 使用PutFullMatrix发送标量场数据到Matlab中
GqL&hbpi 7. 用Matlab画出照度数据
>W] Wc4\ 8. 在Matlab计算照度平均值
