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。 _p_F v>>: ;JZXSM-3 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: ze4/XR enableservice('AutomationServer', true) Fe= 4^. enableservice('AutomationServer') ITsJjcYw Xs!eV 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。 <5X@r#Lz -"cN9RF 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: [=9R5.)c 1. 在FRED脚本编辑界面找到参考. $<aBawLZO 2. 找到Matlab Automation Server Type Library QqwXFk 3. 将名字改为MLAPP `Ch6"=t {[s<\<~B* ScTqnY$v 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。 @i`gR% {$EXI]f 图 编辑/参考 4/h2_
