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+Oc G)>W'yxQ 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: 6`\]derSon enableservice('AutomationServer', true) ngulc v enableservice('AutomationServer') ,(G%e
_nT{g 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。 V@=V5bZLs vAP{;Q0i 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: 7=4 A;Ybq 1. 在FRED脚本编辑界面找到参考.

'UM!*fk7C 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。 ghk5rl$ D 7shiv|,
