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。 %;SOe9 $6BD6\@ 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: qOyg&]7 enableservice('AutomationServer', true) p Rt=5WZ enableservice('AutomationServer') .t/XW++ D[.;-4"_ 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 <2cl1Fb r!qr'Ht< 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: mL!)(Bb 1. 在FRED脚本编辑界面找到参考. g~5$X{ 2. 找到Matlab Automation Server Type Library n[jyhBf\W 3. 将名字改为MLAPP -}l iG l;4},N ,tdV-9N[O 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。 0]tr&BLl* <&n\)R4C1 图 编辑/参考 l]BIFZ~ wnaT~r@U' 现在将脚本代码公布如下,此脚本执行如下几个步骤: CJ*8x7-t 1. 创建Matlab服务器。
