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。 a +'k#m H jhgu= 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： u7&q(Z&&O enableservice('AutomationServer', true) 6/Iq@BZ& enableservice('AutomationServer') I3gl+)Q  q QcQnd2K 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。
