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。 Ne<"o]_M y#AwuC K 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: @83h/Wcxd enableservice('AutomationServer', true) T{={uzQeJJ enableservice('AutomationServer') ^IxT.g )K8k3]y& 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。 Oph4&Ip[w fn zj@_{| 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: j w)Lofn 1. 在FRED脚本编辑界面找到参考. j[XA"DZR< 2. 找到Matlab Automation Server Type Library ?gb"S, 3. 将名字改为MLAPP ?=]`X=g6 sD$
