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。 g9>~HF$U h;M3yTM- 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: E zT`,#b enableservice('AutomationServer', true) ;l!`C' :' enableservice('AutomationServer') GozPvR^/ n=!uNu7 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。 TFH&(_b S`=WF^ 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: ~W{-Q. 1. 在FRED脚本编辑界面找到参考. AW8'RfC. 2. 找到Matlab Automation Server Type Library (Hp' B))2 3. 将名字改为MLAPP gH7z 8r:M*25 .i/m 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。 npH?4S-8G 2<r\/-#pU 图 编辑/参考 Z4q~@|+%
