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。 #J|DW C!#d "|6763.{4 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: qg9VK'3o enableservice('AutomationServer', true) `2PvE4]%p enableservice('AutomationServer') p?e-`xs O]%Vh
l 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。 AH'4k(- L1u(\zw 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: b1Fd]4H3P 1. 在FRED脚本编辑界面找到参考.
