g7 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。
Fy=GU<&AI k<9,Ypa
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:
^{Y, `F enableservice('AutomationServer', true)
c2E /-n4K@ enableservice('AutomationServer')
"#d$$ 8
$S6(V}yh 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
LRJX>+@ `Skvqo(5: 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
QQJGqM3a2 1. 在FRED脚本编辑界面找到参考.
Aiq Kf= 2. 找到Matlab Automation Server Type Library
?8>a;0 3. 将名字改为MLAPP
PR{ubMn #7uH>\r 6{2y$'m8 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。
