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。 _P.+[RS@ X(kyu,w 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： 9{\e E]0 enableservice('AutomationServer', true) 2i`N 26On enableservice('AutomationServer') 4^(u6tX5|+  I `:nb 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。 TcA+ov>TD l/0TNOA 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： }6b =2Z} 1. 在FRED脚本编辑界面找到参考.

\8aE 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。 #!0le :_ 2
