[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。 "yWw3(V2>  
nM,:f)z  
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： swKkY`g  
enableservice('AutomationServer', true) *rxr:y#Ve  
enableservice('AutomationServer') ,g*!NK_:5t  
?t#wK}d.  
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。 :^;c(>u{

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： =2Y;)wrF  
1. 在FRED脚本编辑界面找到参考. jr6_|(0 i6  
2. 找到Matlab Automation Server Type Library VYvfx  
3. 将名字改为MLAPP A1WUK=P

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。 e8m,q~%#/

1. 创建Matlab服务器。 Gp"GTPT{

3. 在探测面追迹光线 \}jMC  
4. 在探测面计算照度 lj4Fg*/Yn  
5. 使用PutWorkspaceData发送照度数据到Matlab h$cm:uks  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ua\t5M5  
7. 用Matlab画出照度数据 d,<ni"  
8. 在Matlab计算照度平均值 sZ;|NAx)  
9. 返回数据到FRED中 ^t>mdxuq
