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。 HUAbq }
Y( 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: A<]
$[2qPj enableservice('AutomationServer', true) X
}`o9]y enableservice('AutomationServer') v.-r %j{I K'}I?H~P_ 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。 4ClSl#X#i p"FWAC! 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: A0>r]<y 1. 在FRED脚本编辑界面找到参考. dVPY07P 2. 找到Matlab Automation Server Type Library 3RX9LJGX 3. 将名字改为MLAPP EJP] E) d[{!^,%x" M&jlUr&l 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。 oiIl\#C bU/4KZ'-^ 图 编辑/参考 aNn4j_V( =:Yrb2gP_\ 现在将脚本代码公布如下,此脚本执行如下几个步骤:
