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。 cj[b ^Wv: dTg`z,^F 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: iqDyE*a enableservice('AutomationServer', true) i5}Z k r enableservice('AutomationServer') >38>R0k35 (A~7>\r + 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。 bTD?uX!^@ zgAU5cw 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: @N Yl4N 1. 在FRED脚本编辑界面找到参考. kZw"a*6 2. 找到Matlab Automation Server Type Library *9j'@2!M 3. 将名字改为MLAPP Pp_4B cdMSC7l! /w?e(v< 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。 {zb'Z Yz ]UvB+M]Lv) 图 编辑/参考 XKjrS
