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。 ? Rk[P
cX< ? *v*fs0 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： DbSR(: enableservice('AutomationServer', true) ;Nw)zS enableservice('AutomationServer') 'T|EwrS j  j s9^~:Tw 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。 Ou4 `#7FR (;;.[4,y 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： y=aWSb2y' 1. 在FRED脚本编辑界面找到参考.
