FRED案例-FRED如何调用Matlab
Z2hRTJJ[A 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。 36.L1!d)pE h6la+l?x 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: t\u0\l> enableservice('AutomationServer', true) wrw~J enableservice('AutomationServer') O_(/uLH
z8jQaI]j 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。 !</5 )B`5: H4Pj 3' 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: lhJT& 1. 在FRED脚本编辑界面找到参考. rEs,o3h?po 2. 找到Matlab Automation Server Type Library >wz-p
nD 3. 将名字改为MLAPP uu]<R@!J !<@k\~9^D C6:<.`iD87 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。 h7kGs^pP 图 编辑/参考 w6v P
