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。 l
\~w(8g<A
nb}* IExd 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: s5? 1w enableservice('AutomationServer', true) E!.>*`)?. enableservice('AutomationServer') nG<_&h
"N'tmzifh 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。 _@I<H\^ Zcq'u
