[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。 ps`j>vX*  
8#,_%<?UVy  
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： Hq>hnCT  
enableservice('AutomationServer', true) ]FvGAG.*  
enableservice('AutomationServer') 0x*|X@6\  
pQ^V<6z}  
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。 u~FVI

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： x_-V{ k  
1. 在FRED脚本编辑界面找到参考. #Q=c.AL{  
2. 找到Matlab Automation Server Type Library a0A=R5_  
3. 将名字改为MLAPP SQ+r'g

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。 m&q0 _nay

1. 创建Matlab服务器。 A{)pzV25

4. 在探测面计算照度 92D~trn  
5. 使用PutWorkspaceData发送照度数据到Matlab
