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。 a:+{f& v:EB*3n5 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: )) Zf|86N enableservice('AutomationServer', true) O1rvaOlr enableservice('AutomationServer') cec9l65d E0BMv/r8b 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。 ,f kcp]} Hh%I0# 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: yTyj'-4 1. 在FRED脚本编辑界面找到参考.
