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。 d&3I>E$UP ( kD?},Z 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: xf3/<x!B enableservice('AutomationServer', true) [eTck73 enableservice('AutomationServer') [s&
y_[S U7Sl@-#| 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。 &~f*q?xR 22H=!.DJ 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: ".7KEnx 1. 在FRED脚本编辑界面找到参考. e^K=8IW 2. 找到Matlab Automation Server Type Library P St|!GST 3. 将名字改为MLAPP +HVG5l RdpQJ)3F /E1c#@ 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。 okW)s*7 j4hUPL7
