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。 ^ytrK
Q |df Pki{ 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: eByz-,{P enableservice('AutomationServer', true) =nS3p6>rZ enableservice('AutomationServer') *&W"bOMH* HC8e>kP9b 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。 WH} y"W "S]TP$O 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: Llo"MO*sr 1. 在FRED脚本编辑界面找到参考. F>l]
