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。 !5ppA FJ/kumq 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: H}A67J9x enableservice('AutomationServer', true) !r$/-8b enableservice('AutomationServer') XMpPG~XdN \;4RD$J 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。 o4d>c{p [mX\Q`)QP 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: iidK}<o 1. 在FRED脚本编辑界面找到参考. )U5AnL 2. 找到Matlab Automation Server Type Library pDW .Pav 3. 将名字改为MLAPP VPK)HzPG, /6g*WX2P1 %h^; "|Z 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。 u)%J5TR .Y Dzb@H$BQ7 图 编辑/参考 w}+jfO9 hD
