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。 O@,i1ha% 0wvU?z%WK 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: >\bPZf)tJ) enableservice('AutomationServer', true) g
i4 enableservice('AutomationServer') yN:>!SQ JQT4N[rEE 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。 q/'MS[C #313
