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。 FBouXu#
gy|o#&e]% 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: +N2ILE8[< enableservice('AutomationServer', true) *u,&?fCl enableservice('AutomationServer') .s41Tc5u T4ugG?B* 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
