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。 C<^S$ Xh~oDnP 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: 3],(oQq^ enableservice('AutomationServer', true) fl_a@QdB# enableservice('AutomationServer') F*:H&, DuQ:82 3b 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。 6,R<8a;Wn cIuCuh0I` 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: FklO#+<: 1. 在FRED脚本编辑界面找到参考. +$^[r 2. 找到Matlab Automation Server Type Library 6p,}?6^ 3. 将名字改为MLAPP 2|M,#2E- r"5\\ qf5* ]<fZW"W<q 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。
