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。 p0b2n a
! *H''.6 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: q,->E<8 enableservice('AutomationServer', true) bFt$u]Yvo enableservice('AutomationServer') v?
VNWK2
MRn;D|Q 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。 pZA0Go2!IN qL
