FRED如何调用Matlab
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。 =H;F{J" fzZ`O{$8 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: jW;g{5X enableservice('AutomationServer', true) L&hv:+3N enableservice('AutomationServer') 0$=w8tP)
%![3?|8~ 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。 E-Y4TBZ* SSysOeD+ 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: $d5}OI"g 1. 在FRED脚本编辑界面找到参考. v /x~L$[ 2. 找到Matlab Automation Server Type Library "wnN
