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。 Ex+E66bE |wM<n 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: 9j>LU<Z enableservice('AutomationServer', true) 24I\smO enableservice('AutomationServer') Hrg -5_ ~m3Tq.sYrY 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。 T9?8@p\}( 4 3G2{ 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: )v+\1 1. 在FRED脚本编辑界面找到参考. }u+cS[#-
