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。 yDE0qUO >8*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: ,cesQ
ou enableservice('AutomationServer', true) +.EP_2f9 enableservice('AutomationServer') c*k%r2' b%-S'@ew 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。 \~(scz$ I1a>w=x!+ 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: ma gZmY~ 1. 在FRED脚本编辑界面找到参考. I*SrKZb 2. 找到Matlab Automation Server Type Library wm'a)B? 3. 将名字改为MLAPP -lb,0 \~r`2p-K kL7n`o 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。 |+aUy^ L/[b~D>T% 图 编辑/参考 YUGEGXw 6w"_sK?
