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。 6 2#dSd}HG d"hW45L 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： " ll
TVB enableservice('AutomationServer', true) 2ID]it\5 enableservice('AutomationServer') [(4s\c  Ok6c E 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。 *u`[2xmuYf vB T]a 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： ; bxL$1 1. 在FRED脚本编辑界面找到参考. xr'gi(.o 2. 找到Matlab Automation Server Type Library d (8X?k.S 3. 将名字改为MLAPP x $
