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。
!]jNVg 8t^;O! 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: DlQ[}5STF enableservice('AutomationServer', true) ko7-%+0|] enableservice('AutomationServer') Ow&'sR'CX 9O0 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。 EssUyF-jwU )eedfb1 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: ?6l, 1. 在FRED脚本编辑界面找到参考. bju,p"J1-E 2. 找到Matlab Automation Server Type Library w1!\L_::Y 3. 将名字改为MLAPP _QtQPK\+ BzG!Rg|J '=G<)z@k 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。 3!L<=X xr7<(:d 图 编辑/参考 "
