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。 i{
" g7 p#eai 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: Vo2{aK; enableservice('AutomationServer', true) sAG#M\A6 enableservice('AutomationServer') ,xeJf6es ,XJ
Xw(LM 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。 n%J{Tcn6 QmpP_eS > 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: A*r6 1. 在FRED脚本编辑界面找到参考. =I}8-AS~V 2. 找到Matlab Automation Server Type Library \q0wY7w 3. 将名字改为MLAPP Hmi]qK[F ?pF7g$>q };z[x2l^ 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。 O"D0+BK79e AP8YY8,
