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。 @6d[=!9 ':}\4j&{E 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: [2koe.?( enableservice('AutomationServer', true) fLVAKn enableservice('AutomationServer') DJ%PWlK5 {U1m.30n 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。 w:l"\Tm s7EinI{^ 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: CJ%I51F`X 1. 在FRED脚本编辑界面找到参考. yBRC*0+Vy 2. 找到Matlab Automation Server Type Library 3[&C g 3. 将名字改为MLAPP <1pEwI~ J=L5=G7( kR9-8I{J 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。 q9NoI(]e or]IZ2^n 图 编辑/参考 Z=
