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。 x Vw1 }|nEbM]# 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:
E/gfX
enableservice('AutomationServer', true) v9Lf|FXo& enableservice('AutomationServer') Ga pM~~
g\*2w
@ 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。 Fz| r[
O8-Z >; 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: ucJ8l(?Qc 1. 在FRED脚本编辑界面找到参考. c2]h.G83 2. 找到Matlab Automation Server Type Library u_b6u@r7 3. 将名字改为MLAPP 4~hP25q )r(e\_n F3x*dq2 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。 pi/&WMZ< 3@1$y`SN
