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。 uGC%3! f! W^W.* ?e` 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： BD$Lf, _ enableservice('AutomationServer', true) 5 -4 enableservice('AutomationServer') 6=%\@  'QpDx&~QP 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。 ./ tZ*sP: (wH+ 0 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： 6Po {tKU 1. 在FRED脚本编辑界面找到参考. ~- aUw}U 2. 找到Matlab Automation Server Type Library lE+Duap: 3. 将名字改为MLAPP R<3 -!p1v CT\rx>[J.6 -{oZK{a1 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。 %f\j)qw AO -~dV 图 编辑/参考 {Z s
