gwDVWhq 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。
R%"'k<`# )i<Qg.@MX 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:
465?,EpS enableservice('AutomationServer', true)
4e?MthJ> enableservice('AutomationServer')
lJt?0;gn
!d&SVS^mo 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。
