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。 z SDRZ! Ezsb'cUa( 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: r6S-G{o enableservice('AutomationServer', true) }K':tX? enableservice('AutomationServer') _uwM%M; Yef=HSzo 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。 }%Mj`Bh -< D7 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: NbgK#; 1. 在FRED脚本编辑界面找到参考. P'%#B&LZo 2. 找到Matlab Automation Server Type Library N3dS%F,_ 3. 将名字改为MLAPP Wi7!J[ B $cjwY$6 ;w>Dqem 在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 WzG]9$v & a,mG5bQ! 图 编辑/参考 ;e
