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。 9qDM0'WuU j=pg5T 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: Rk5#5R n enableservice('AutomationServer', true) )@9Eq|jMC enableservice('AutomationServer') E-1u_7
yR~$i3Z* 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。
kMW9UUw Y;R,ph.a 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: u3Z]!l 1. 在FRED脚本编辑界面找到参考. P$z%:Q 2. 找到Matlab Automation Server Type Library Ytc[ kp 3. 将名字改为MLAPP dG+$!*6Z N( 7(~D=)B uhj]le! 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。 A3.I|/ -'O|D}
