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。 ;h~v,h 1F,>siuh , 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: |Y tZOQu enableservice('AutomationServer', true) 5>x?2rp enableservice('AutomationServer') wZnv*t_
|& Pa`=sp 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。 3:g~@PB =O
