FRED案例-FRED如何调用Matlab
6,1b=2G 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。 JJV0R}z?TV QU{Ech' 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: 6*9}4` enableservice('AutomationServer', true) ~/_9P Fk enableservice('AutomationServer') -3Avs9`5
h9$ Fx 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。 4@ILw _2fkb=2@ 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: Zn:R
