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。 P\nC?!Q%c TX [%(ft 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: PVOx`<ng enableservice('AutomationServer', true) ^:=f^N=^ enableservice('AutomationServer') h"+ `13
3AcD,,M>> 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。 ;gg\;i}^ a->3`c 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: bGF7Zh9 1. 在FRED脚本编辑界面找到参考. PU<PhuMd
2. 找到Matlab Automation Server Type Library rN)V[5R#M 3. 将名字改为MLAPP O1&b]C# &opd2 R(Kk{c:-@ 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。 o=J9 SQ*k =4*r
