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。 ,0,FzxX0! uOeal^uS 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: WEe7\bWF enableservice('AutomationServer', true) +Tu?PuT7k enableservice('AutomationServer') 1u7D:h>#
V0_tk" 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。 @WS77d~S ^ex\S8j 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: m<-!~ ew 1. 在FRED脚本编辑界面找到参考. QwWd"Of 2. 找到Matlab Automation Server Type Library 7]zZdqG&p` 3. 将名字改为MLAPP Fc5t,P 0>7Ij7\[8 }URdoTOvb 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。 2<I=xWwFA Rh|9F yN
