FRED案例-FRED如何调用Matlab
ew8Manx 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。 BH?fFe&J:` Q .cL1uHc 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: *3!ixDX[r enableservice('AutomationServer', true) x*F_XE1#M enableservice('AutomationServer') 'C1yqkIa`
;8<lgZ9H< 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。 AaJnRtBS~ (0bXsfe 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: e&XJK*Wf 1. 在FRED脚本编辑界面找到参考. 0Y ld!L 2. 找到Matlab Automation Server Type Library + WFa4NZ 3. 将名字改为MLAPP Tn\59 ( DUu~s,A tumYZ)nW 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。 7
