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。 183'1Z$KA WY<ip< 配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： iM} cd$r{ enableservice('AutomationServer', true) 80:na7$)# enableservice('AutomationServer') +J.^JXyp0  SznNvd < 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。 J+Y& a&j.
