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。 ve:Oe{Ie{ d!4TwpIgx 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: !Z
0U_*& enableservice('AutomationServer', true) s 0_*^cZ enableservice('AutomationServer') ,L lYRj 5 pwk Te 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。 v~yw-}fk% 2r;h"> 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: K&zW+C b 1. 在FRED脚本编辑界面找到参考. ^b|I^TN0 2. 找到Matlab Automation Server Type Library RRpY%-8M 3. 将名字改为MLAPP =@S
a\; >{9VXSc D.Cn`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。 5Zd oem QnP?j& 图 编辑/参考 r
