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。 zt!> @.G;dL.f{ 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: K>\v<!%a enableservice('AutomationServer', true) q"f7$ enableservice('AutomationServer') jsKKg^g
l6MBnvi 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。 .~^A!t n#4T o;CS 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: ye}86{l 1. 在FRED脚本编辑界面找到参考. tv]9n8v 2. 找到Matlab Automation Server Type Library
7(o:J 3. 将名字改为MLAPP *N6sxFs (Bpn9}F-V. mWLi XKnb 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。 ChNT;G<6$ !9V;
