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。 '?' l;#^i< Oc0a77@ 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: 8U"v6S~A%Q enableservice('AutomationServer', true) H [\o RId enableservice('AutomationServer') :gibfk]C
@+2=g WH 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。 r.&Vw|*> ? pmHFlx 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: (_]~wi-, 1. 在FRED脚本编辑界面找到参考. z (wc0I 2. 找到Matlab Automation Server Type Library OU_gdp 3. 将名字改为MLAPP !sP{gi#= K#d`Hyx `wEb<H
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。 S!CC
