[技术]FRED如何调用Matlab [复制链接]

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。 d--6<_q  
7X$pgNRx/a  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： ZS_ z  
enableservice('AutomationServer', true) jgpF+V-n$  
enableservice('AutomationServer') 4_CXs.v1  
UNrO$aX!1'  
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。 vPy."/[u  
Opy{i#>  
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 Kd:O

1. 在FRED脚本编辑界面找到参考. y?}<SnjP:  
2. 找到Matlab Automation Server Type Library ky]L`

3. 将名字改为MLAPP -=1>t3~\

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。 Ve"M8-{oKk
