FRED如何调用Matlab
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。 x^_Wfkch] r:K)Q@ 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: 3P Twpq1 enableservice('AutomationServer', true) f|Kd{ $VO enableservice('AutomationServer') 3 2Q/4
!e6;@ * 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 D.)$\Caq ,$5; 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: uxk&5RY 1. 在FRED脚本编辑界面找到参考. #{7= 2. 找到Matlab Automation Server Type Library udB:ys 3. 将名字改为MLAPP $1oU^VY OTd=(dwh DCX4!,ZF 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。 {r.#R|
