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。 W>
-E.#!_ G\aLg 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: JWm^RQ enableservice('AutomationServer', true) z)?#UdBQv enableservice('AutomationServer') :6Pc m3 =-s20mdj 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。 (fI&("; t BD-c 0-+m 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: Ubos#hP 1. 在FRED脚本编辑界面找到参考. 3I{ta/( 2. 找到Matlab Automation Server Type Library $y]||tX 3. 将名字改为MLAPP { ves@p>? *~lgU4 Ns(L1'9= 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。 (gJ
