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。 wN=;i# 2`?!+") 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： $}GTG'*. enableservice('AutomationServer', true) IiJZ 5'{ enableservice('AutomationServer') ,7_4 z]jK  N&,]^>^u 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。 [?k8}B)mHB |[ $~\MU 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： SaOYu &> 1. 在FRED脚本编辑界面找到参考. :A 1: 2. 找到Matlab Automation Server Type Library 5!X1G8h)uy 3. 将名字改为MLAPP Oy57 $ =(HeF.! 3g~' 5Ao 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。 LR( -< " ;30 nd= 图 编辑/参考 z (?=Iv3 "Gb1K9A
