FRED如何调用Matlab
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。 N),Zb^~nw *|4~
0w 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: lh5k@\X enableservice('AutomationServer', true) (K2 p3M^ enableservice('AutomationServer') 5[ @4($q8
\F<]l6E 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 =|jOio=s: l,d8%\ 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: J"SAA0)@ 1. 在FRED脚本编辑界面找到参考. =,(Ba' 2. 找到Matlab Automation Server Type Library &'(:xjN 3. 将名字改为MLAPP 7gJ`G@y d$>1 2>> D9Q%*DLd$_ 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 :AAqMa air{1="<-
