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。 0 #pjfc `: #s$b\"4 配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： L-hK(W!8pt enableservice('AutomationServer', true) }S<2({GI enableservice('AutomationServer') 'Y IFHn$!  (~:k70V5 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。 rlT[tOVAY l=8)_z;~D 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： `zGK$,[% 1. 在FRED脚本编辑界面找到参考.
