[技术]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。 &3jq'@6

!Cu%4  
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： $}{u6*u.,  
enableservice('AutomationServer', true) 0zSRk]i.f  
enableservice('AutomationServer') .I6:iB  
lu]Z2xSv  
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。 m 6Xex.d

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： H|E{n/g  
1. 在FRED脚本编辑界面找到参考.

2. 找到Matlab Automation Server Type Library ,&wTUS\  
3. 将名字改为MLAPP ||{V*"+\  
k>W5ts2+  
y;0k |C
 
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。 UKIDFDn6_

现在将脚本代码公布如下，此脚本执行如下几个步骤： @uIY+_E40g  
1. 创建Matlab服务器。 WK{{U$:$  
2. 移动探测面对于前一聚焦面的位置。 t>04nN_@,s  
3. 在探测面追迹光线 ?dWfupO{  
4. 在探测面计算照度 3YtFO;-  
5. 使用PutWorkspaceData发送照度数据到Matlab QuJ~h}k  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $_
2S,3 }  
7. 用Matlab画出照度数据 SUSam/xeg"  
8. 在Matlab计算照度平均值 =1rq?M eX  
9. 返回数据到FRED中 |FF"vRi8a7
