[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。 ooAZ,l=8

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： :b=0_<G
 
enableservice('AutomationServer', true) k8ck#%#}Wu  
enableservice('AutomationServer') X*~YCF[_  
-K!-a'J  
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。 -

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： ;CW$/^QNr5  
1. 在FRED脚本编辑界面找到参考. ~!;3W!@(E  
2. 找到Matlab Automation Server Type Library D%A-& =  
3. 将名字改为MLAPP H~@h #6

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。 EAfSbK3z

4. 在探测面计算照度 .DQ]q o]OG  
5. 使用PutWorkspaceData发送照度数据到Matlab x#^kv)  
6. 使用PutFullMatrix发送标量场数据到Matlab中 (}:xs,Ax  
7. 用Matlab画出照度数据 %9lxE[/
