[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。 o3"Nxq"U  
/0Jf/-}ovn  
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： i:a*6b.U@N  
enableservice('AutomationServer', true) Iuyq!R4:7  
enableservice('AutomationServer') a}e GB +  
dhX$b!DA  
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。 f+cN'jH E

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： u^O!5 'D%  
1. 在FRED脚本编辑界面找到参考. nt&"? /s  
2. 找到Matlab Automation Server Type Library M(^_/1Z  
3. 将名字改为MLAPP H#S`m

vfd<qdi3p(  
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。 oE.Ckz~*d

现在将脚本代码公布如下，此脚本执行如下几个步骤： 2tb+3K1  
1. 创建Matlab服务器。 vbD""  
2. 移动探测面对于前一聚焦面的位置。 sYq:2Wn>8Q  
3. 在探测面追迹光线 _1?nLx7n  
4. 在探测面计算照度 Z2U6<4?1%  
5. 使用PutWorkspaceData发送照度数据到Matlab n^q%_60H  
6. 使用PutFullMatrix发送标量场数据到Matlab中 \0W0o5c$  
7. 用Matlab画出照度数据 s TVX/Q  
8. 在Matlab计算照度平均值  >akC  
9. 返回数据到FRED中 {2%'=v
