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。 m+gG &`&u 5tCq}]q#P 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: I\4`90uBN enableservice('AutomationServer', true) _ L:w;Oy9T enableservice('AutomationServer') ThQEQ6y FLnAN; 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。 v=Bh
