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。 ze'.Y%] 2N~ E' 25 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: 1Xyp/X2rI enableservice('AutomationServer', true) *C,N'M<u enableservice('AutomationServer') K`nJVc
>!9h6BoGV 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。 ^ft]b2i mYNEz
