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。 Tfytc$aQ s
+Q'\? 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: IW>\\&pJ enableservice('AutomationServer', true) KvvG
H-] enableservice('AutomationServer') v(GT+i)|
Fs_zNN 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。 qmF+@R&^i .
g8WMm 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: L?&Trq7i 1. 在FRED脚本编辑界面找到参考. !h.bD/?K 2. 找到Matlab Automation Server Type Library &0Bs?oq_ 3. 将名字改为MLAPP lHc|:vG? +ab#2~,) m`!Vryf 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。 +eVm+4WK /4Sul*{hc
