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。 k`A39ln7wu So8
Dwz? 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: eV/oY1B]< enableservice('AutomationServer', true) u"m(a:jQ enableservice('AutomationServer') IGT9}24 q mv0 LU 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。 h_+ nxx/26{
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: %[s%H)e) 1. 在FRED脚本编辑界面找到参考. NdSuOkwwt 2. 找到Matlab Automation Server Type Library EpyMc+.Ze' 3. 将名字改为MLAPP kP^A~ZO. mo] l_' y+w,j] 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。 (Nk[ys}%* {V[}#Mf 图 编辑/参考 tq3Rc}
