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。 }"Clv/3_ 3s;^p,9
Y 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: *lc|iq\ enableservice('AutomationServer', true) NYw>Z>TD8c enableservice('AutomationServer') %g: 6QS|
Q\rf J|| 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。 f3^Anaa]l Zjd9@ 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: 6Z.Fyte 1. 在FRED脚本编辑界面找到参考. xa8;"Y~"bg 2. 找到Matlab Automation Server Type Library ;Nk,bb K 3. 将名字改为MLAPP k'QI`@l&l g8kS}7/ Ym% XCl 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。 TXdo,DPv7 4K5
