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。 |Cv!,]9:r H_a[)DT 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: >MZ/|`[M enableservice('AutomationServer', true) ="+#W6bZT enableservice('AutomationServer') ?uu*L6
j2k"cmsKh 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。 !$JT e kiEa<-] 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: J.a]K[ci 1. 在FRED脚本编辑界面找到参考. *dQSw)R 2. 找到Matlab Automation Server Type Library Gc?a +T 3. 将名字改为MLAPP 9up3[F$ ("KF'fp&M2 4#D,?eA7 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。 -).C _a, s
