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[Kr=:Jp $axaI$bE 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: \C/`?"4w enableservice('AutomationServer', true) f==o
enableservice('AutomationServer') A}OV>y M
J U}XSb 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。 JWlH(-U4| }1z=
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: s2b!Nib 1. 在FRED脚本编辑界面找到参考. }@SZ!-t%rD 2. 找到Matlab Automation Server Type Library @bfaAh~ 3. 将名字改为MLAPP 6\OSIxJZF (U/ 6~r'.L Ny\iRU)fN 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。 Qn[4 &nUD uC 5mxZ
