FRED如何调用Matlab
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。 G+N1#0,q { Z
k^J 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: iXy1{=BDv enableservice('AutomationServer', true) ~<!j]@. enableservice('AutomationServer') M>Q ZN
hy~[7:/<I& 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。 ~2\Sn-` EA(4xj&:U 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: Q k}RcP 1. 在FRED脚本编辑界面找到参考. =V|jd'iwx 2. 找到Matlab Automation Server Type Library o3hgkoF 3. 将名字改为MLAPP we[+6Z6J U2m#BMV -9FGFBm4] 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。 dJ
