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。 jujhK'\ ;i)NP 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: }#u.Of`6" enableservice('AutomationServer', true) i#&iT P` enableservice('AutomationServer') A#yZh\# B_gzpS] 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。 1BA/$8G >FVBn;1 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: Hwz.5hV" 1. 在FRED脚本编辑界面找到参考. +f}u.T_# 2. 找到Matlab Automation Server Type Library 4"om;+\ 3. 将名字改为MLAPP DRDn;j +N|}6e :7WeR0*% 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。 nY>UYSv ` XvuyH 图 编辑/参考 .T2P%Jn.
