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。 8.6no 1v+JCOy 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: !]n{l_5r enableservice('AutomationServer', true) RI7qsm6RN enableservice('AutomationServer') $yP'k&b!
Z_ iQU1
结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 .N'%hh Q%_!xQP` 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: y$+!%y* 1. 在FRED脚本编辑界面找到参考. 9u-M! $ 2. 找到Matlab Automation Server Type Library Off: ~ 3. 将名字改为MLAPP HY@kw>I Xuz8"b5^Zx 81%qM7v9H 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。 dK-
