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!R`b9_U f 0/q{* 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: q) e*eN enableservice('AutomationServer', true) o^d enableservice('AutomationServer') BS?rKtdm( X-yS9E 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。 ,_'Z Jlx %8KbVjn 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: JGlp7wro 1. 在FRED脚本编辑界面找到参考. 4g+o/+6!4 2. 找到Matlab Automation Server Type Library 7$kTeKiP 3. 将名字改为MLAPP V4<f4|IL q] '2'"k xy^z_` 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。 {>yy3(N ATD4%|a9h 图 编辑/参考 _dVA^m T
