[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。 9L>?N:%5  
:9hGL  
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： w5>[hQR\  
enableservice('AutomationServer', true) ei5YxV6I  
enableservice('AutomationServer') F{x+1hct0  
qPPe)IM'Sc  
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。 5_(\Cd<#

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： cKVFykwM  
1. 在FRED脚本编辑界面找到参考. Z!g6uV+.5  
2. 找到Matlab Automation Server Type Library *^-AOSVt,  
3. 将名字改为MLAPP VlV X

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。 KZ5%q.

1. 创建Matlab服务器。

4. 在探测面计算照度 t=Oq

5. 使用PutWorkspaceData发送照度数据到Matlab E ASnh   
6. 使用PutFullMatrix发送标量场数据到Matlab中 S/E&&{`ls  
7. 用Matlab画出照度数据 Z:{| ?4
