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。 W{RZ@3ZY "_^vQ1M]Z 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: LUs)"ZAi| enableservice('AutomationServer', true) |` |#-xu enableservice('AutomationServer') .}9Lj %g_)_ ~ 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。 `.z"Q%uz u4#YZOiY)A 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: aP$it6Z 1. 在FRED脚本编辑界面找到参考. ty8>(N(~ 2. 找到Matlab Automation Server Type Library &t~NR$@ 3. 将名字改为MLAPP vX@TZet0 Tbp;xv_qo n!dXjInV 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。 l|81_B C" TMsc5E 图 编辑/参考 G!
