PSrx! 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。
:\](m64z; "EW8ll7r 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:
FOaA}D `] enableservice('AutomationServer', true)
~cz}C("Z enableservice('AutomationServer')
[hJ1]RW8
s8j |>R|k 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。
