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。 -9{N7H !% W5@tN 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: oz=ULPZ%
enableservice('AutomationServer', true) _dk[k@5W{' enableservice('AutomationServer') *Ts$Hj[ Ff/Ap&0+ 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。 Posz|u<x ]m 3cm 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: Q<V1`e 1. 在FRED脚本编辑界面找到参考. 6?M/71 2. 找到Matlab Automation Server Type Library nD
