FRED案例-FRED如何调用Matlab
`~[zIq:}7 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。 kssS,Ogf\_ s,N%sO; 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: ;g: TsYwM enableservice('AutomationServer', true) za'Eom-<u enableservice('AutomationServer') <0vQHND,3
}-k<>~FA 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。 ]v@#3,BV /yyed{q 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: _wKFT> 1. 在FRED脚本编辑界面找到参考. ?7^H1L 2. 找到Matlab Automation Server Type Library *@lNL=%R 3. 将名字改为MLAPP /s(/6~D| QP)-O*+AA 4QdY"s(n 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。 s
