[分享]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。 'S@h._q  
Hd2Sou4-j  
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： WH/
r$.&  
enableservice('AutomationServer', true) .CQ IN]iD  
enableservice('AutomationServer') jP@H$$-=wH  
bYgrKz@uK  
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。 Ur?a%]

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： l')?w]|  
1. 在FRED脚本编辑界面找到参考. Le|Ho^h,Y
 
2. 找到Matlab Automation Server Type Library `)1_^# k  
3. 将名字改为MLAPP H5^'J`0\

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。 /NMd GKr
