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。 QTeF R&q8 6hLNJ 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： q%DVDq( z enableservice('AutomationServer', true) Z6NJ)XQy6F enableservice('AutomationServer') J
&{qppN  >/8ru*Oc 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 >81dO]H .|U4N/XN%q 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： XynU/Go, 1. 在FRED脚本编辑界面找到参考. ~Vwk:+): 2. 找到Matlab Automation Server Type Library Gee~>:_Q{J 3. 将名字改为MLAPP "$]ls9 -%n nZ&T8@m Mp^^!AP 9 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 tSI& "- +O&RBEa[ 图 编辑/参考 @X
