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。 QRHM#v S |vY|jaV} 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: 3\j3vcuy enableservice('AutomationServer', true) qF4=MQm\aE enableservice('AutomationServer') C^ZDUj`
GB{Q)L 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。 ,:pKNWY)Q g-<[* nF 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: ;"]?&ri 1. 在FRED脚本编辑界面找到参考. kk ZMoK 2. 找到Matlab Automation Server Type Library !yu-MpeG 3. 将名字改为MLAPP O5dBI_ (|sqN8SbA MrhJk 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。 XL`i9kV? $!K,5^+
