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。 `0@z"D5c b# ='^W3 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: 1tGgDbJU enableservice('AutomationServer', true) u"Y]P*[k enableservice('AutomationServer') L!y"d!6C
-?fR|[\[U 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。 W.[BPR 6tm\L 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: onnugj3 1. 在FRED脚本编辑界面找到参考. >lLo4M 3 2. 找到Matlab Automation Server Type Library B^q<2S; 3. 将名字改为MLAPP "~\*If :1_mfX (Ilsk{aB;A 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。 -;Uj|^ iLtc
