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。 AJ? r,!) 3kIN~/<R+7 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： otl0J Ht*+ enableservice('AutomationServer', true) 6?mibvK enableservice('AutomationServer') C] eSizS.  ~'i Ho]9O 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。 %C'?@,7C EC6DW= 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： F2 dHH^ 1. 在FRED脚本编辑界面找到参考.
