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。 |e;z"-3 k+GK1Yl 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: K2o0L5Lke enableservice('AutomationServer', true) 3k[<4- enableservice('AutomationServer') R qjDMN: T0"0/{5-_ 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。 otH[?c?BT M*@aA
