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。 S~1>q+<Q R5LzqT,/N: 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: $or?7 w> enableservice('AutomationServer', true) fH.:#O: enableservice('AutomationServer') C24[brf !F0MLvdX7^ 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 %?^T^P V:h-K`~/ 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: GS |sx 1. 在FRED脚本编辑界面找到参考. 9X8{"J 2. 找到Matlab Automation Server Type Library <uP> 3. 将名字改为MLAPP (~/VP3.S n{F$,a .O[RE_j 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。 $'3`$
