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。 <4O=[Q 5S tX p)o >" 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： G)e 20Mst enableservice('AutomationServer', true) vW4 f 3(/ enableservice('AutomationServer') Wc] Fg9E  \ \/X+4|o' 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。 gf3/ kll9 m Yy3KqYu 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： '.dW>7 1. 在FRED脚本编辑界面找到参考. =Wjm_Rvk9 2. 找到Matlab Automation Server Type Library p [/n[@<8= 3. 将名字改为MLAPP ' l!QGKz ~z
