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。 e_C9VNP ">b~k;M? 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: 99Xbp P55 enableservice('AutomationServer', true) h&|wqna enableservice('AutomationServer') iG<rB-"
6;/>asf 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。 (s?`*i:2 Lo,z7"8 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: 8J|pj4ce 1. 在FRED脚本编辑界面找到参考. 5j(3pV`_ 2. 找到Matlab Automation Server Type Library <:#O*Y{ 3. 将名字改为MLAPP p/V X|.M9zIx 1](5wK-Z 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。 S312h'K
