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[v<mo[s Viw,YkC 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： n[K%X s) enableservice('AutomationServer', true) c1+z(NQ3 enableservice('AutomationServer') U"Bge\6x=  C Q iHk 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。 PX&}g-M9 L?0IUGY 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： 2h*aWBLk 1. 在FRED脚本编辑界面找到参考.
