[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。 -}*YfwK

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： ! .|\}=[e  
enableservice('AutomationServer', true) dD8f`*"*=  
enableservice('AutomationServer') }xM >F%  
Vam4/6  
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。 [S!_ubP5

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： rYMHc@a9(  
1. 在FRED脚本编辑界面找到参考. U: Q&sq8U  
2. 找到Matlab Automation Server Type Library q

3. 将名字改为MLAPP Od:,r

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。 zcNv T

1. 创建Matlab服务器。 &*#- %<=1

4. 在探测面计算照度 ,2YkQ/>  
5. 使用PutWorkspaceData发送照度数据到Matlab 36U zfBa  
6. 使用PutFullMatrix发送标量场数据到Matlab中 qj5V<c;h%W  
7. 用Matlab画出照度数据 wd`lN,WiW
