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。 Lg4I6 G .Qeml4(`3 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: yS:1F
PA$_ enableservice('AutomationServer', true) Z<0+<tt enableservice('AutomationServer') 5&*B2ZBzH ewcgg 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。 HR83{B21 "ZyWU f 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: ,0Y5O?pu\ 1. 在FRED脚本编辑界面找到参考.
