[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。 o2W^!#]=
 
E>Lgf&R#W  
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： H?tX^HO:q  
enableservice('AutomationServer', true) <_~e/+_.  
enableservice('AutomationServer') j-9Zzgr  
h#(J6ht  
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。 :FX|9h

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： -8m3L  
1. 在FRED脚本编辑界面找到参考. 
?yy,3:  
2. 找到Matlab Automation Server Type Library #MAXH7[  
3. 将名字改为MLAPP ?OF9{$m3?

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。 #gSLFM{p

现在将脚本代码公布如下，此脚本执行如下几个步骤： LGT?/gup  
1. 创建Matlab服务器。 R/Z zmb{  
2. 移动探测面对于前一聚焦面的位置。 l' 2C/#8F  
3. 在探测面追迹光线 LZ<^b6Dxk  
4. 在探测面计算照度 }0~X)Vgm(  
5. 使用PutWorkspaceData发送照度数据到Matlab }) Zcw1g  
6. 使用PutFullMatrix发送标量场数据到Matlab中 (

7. 用Matlab画出照度数据 J/B`c(  
8. 在Matlab计算照度平均值 +a0` ,Jc  
9. 返回数据到FRED中 #dDM "s
