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。 ~Ob8i 1S> &LU'.jY 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: aW@oE
~` enableservice('AutomationServer', true) IH3FK!>6 enableservice('AutomationServer') HP$K.a7H
VC=6uB 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 B/Ba5z"r$ $'$>UFR 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: ?0npEz| 1. 在FRED脚本编辑界面找到参考. ,35Ag#va 2. 找到Matlab Automation Server Type Library Ve14rn 3. 将名字改为MLAPP P{lh)m> #'NY}6cb$ A[ 1)!e 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。 ;Prg'R[o; Z1]"[U[;
