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。 R<
@o]p Icf 4OAx 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: $~c?qU enableservice('AutomationServer', true) :"? boA#L enableservice('AutomationServer') K_j$iHqLF 3`_jNPV1 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。 INSI$tA~ |VMc,_D 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: %||}WT-wv 1. 在FRED脚本编辑界面找到参考.
