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。 m+8:_0x " /Z]nV2$n)V 配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： [z\ba L| enableservice('AutomationServer', true) M
hW9^? enableservice('AutomationServer') b3_P ??yp  Bx \ o8k 结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 L UxDP#~7 ,[p pETz 在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： 0\"#X a+}8 1. 在FRED脚本编辑界面找到参考. &c "!Y)%G 2. 找到Matlab Automation Server Type Library ?7)v:$(G} 3. 将名字改为MLAPP |J`v
