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。 c0hdLl; 5 G`WzJS*}v 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： dr>]+H=3 E enableservice('AutomationServer', true) l58l enableservice('AutomationServer') EKJH_!%  BDnBBbBrz 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。 A1 b6Zt >: fJhF@ 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： +@ ^47Xu^ 1. 在FRED脚本编辑界面找到参考. yT 2vO_rH 2. 找到Matlab Automation Server Type Library ^
