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。 nG(|7x
,"HpV 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:
=}1~~ enableservice('AutomationServer', true) a}I z enableservice('AutomationServer') "MVN/Gl RWEgUDX^/ 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。 5E!|on 5tbiNm^X 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: r%?}5"* 1. 在FRED脚本编辑界面找到参考. =*O9)$b 2. 找到Matlab Automation Server Type Library @o-evH;G 3. 将名字改为MLAPP vA $BBXX 8i+jFSZ$ v(WL 3[y; 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_ u7
