FRED如何调用Matlab
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。 4hj|cCrO |L ev.,,Ph 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: 0=YI@@n) enableservice('AutomationServer', true) Z T%5T}i enableservice('AutomationServer') M= (u]%\
9'B `]/L 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。 2^7`mES @yYkti;4- 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: ~"!fP3"e 1. 在FRED脚本编辑界面找到参考. 2,b$7xaf 2. 找到Matlab Automation Server Type Library l/5
hp. 3. 将名字改为MLAPP 6gDN`e,@ z$sT !QL~ \FaP|28h 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。 ;xTpE2 -~ e0 ecD3
