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。 hy:K) _
EKT"pL-EY 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: z<BwV
/fH} enableservice('AutomationServer', true) [92bGR{ enableservice('AutomationServer') J1Y3>40
,-BZsZ0~ 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。 y)Lyo'` BCHI@a 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: hpticW| 1. 在FRED脚本编辑界面找到参考. 2K'}Vm+ 2. 找到Matlab Automation Server Type Library xX])IZD 3. 将名字改为MLAPP L^nS%lm dGc>EZSdj ~K|o@LK 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。 LZu_-I k_Edug~B
