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。 NW9n LE^G&<! 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: FyL_xu\e enableservice('AutomationServer', true) M(q'%XL^ enableservice('AutomationServer') ^n.WZUk b4 #R! 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。 ;oOv/3 )ukpJ z"" 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: @DAF 6ygs 1. 在FRED脚本编辑界面找到参考.
