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。 QX/]gX y<uE-4 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: *(VbPp_H_ enableservice('AutomationServer', true) Heohe|an enableservice('AutomationServer') 83xd@-czgh
dp< auA 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。 7NUenCdc 2HVCXegq 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: w}b<D#0XC 1. 在FRED脚本编辑界面找到参考. eHROBxH& 2. 找到Matlab Automation Server Type Library Deog4Ol"/ 3. 将名字改为MLAPP Q^ q=!/qQ 9T]va]w?# :b,o B==% 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。 _"v~"k 90^ H>Sf[8w)%
