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。 _fE$KaP ]o3K 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 1XPYI enableservice('AutomationServer', true) ?:+sjHzXT enableservice('AutomationServer') =--oH'P=M
G%5ZG$as 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。 K0C3s 1yV+~)by3 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: g=L80$1 1. 在FRED脚本编辑界面找到参考. ^SC2k LI 2. 找到Matlab Automation Server Type Library r%412# 3. 将名字改为MLAPP ;\(X;kQi <tT.m[q g U2vM|7]VP 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。 Y=\:fa ne9-
