[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。 E+Bc>xl@m  
}F]Z1('  
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： wS=vm}}u  
enableservice('AutomationServer', true) bpc1>?  
enableservice('AutomationServer') k[8F: T-  
6'r;6T *  
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。 ~Z5AImR|

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： 45 ^ Z5t  
1. 在FRED脚本编辑界面找到参考. vN(~}gOd\  
2. 找到Matlab Automation Server Type Library >T;!Z5L1  
3. 将名字改为MLAPP y^H5iB[SPL

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。 -;g

1. 创建Matlab服务器。 YH58p&up

4. 在探测面计算照度 ]?]M5rP  
5. 使用PutWorkspaceData发送照度数据到Matlab _=0Ja S>M.  
6. 使用PutFullMatrix发送标量场数据到Matlab中 !BVCuuM>w
