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。 8XfOM f~d` #pD=TMefC 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： wO %617Av enableservice('AutomationServer', true) <0/)v
J-
9 enableservice('AutomationServer') !bW^G}
<t  W$}2
$}r0U 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。 s2tNQtq 0W j;_E0j# 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： - Lsl 1. 在FRED脚本编辑界面找到参考. * P12d 2. 找到Matlab Automation Server Type Library So NgDFD 3. 将名字改为MLAPP mt *Dx >)`*:_{ U,< ?]h 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。 pfMmDl5| 5 yL"=3&+ 图 编辑/参考 +D h?M Qt?
