[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。 u-.L^!k  
[cpNiw4e  
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： /gw Cwyo  
enableservice('AutomationServer', true)  AP w6  
enableservice('AutomationServer')  `{}@@]  
( 3;`bvYH"  
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。 (oYW]c}G,

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： *Hu

1. 在FRED脚本编辑界面找到参考. Pfan7fq+  
2. 找到Matlab Automation Server Type Library 1JeJxzv>C  
3. 将名字改为MLAPP 3dm'xetM

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。 /s`;9)G]9

现在将脚本代码公布如下，此脚本执行如下几个步骤： D9o*8h2$  
1. 创建Matlab服务器。 n(R_#,Hs  
2. 移动探测面对于前一聚焦面的位置。 o](.368+4  
3. 在探测面追迹光线 h=[-Er'B  
4. 在探测面计算照度 ?v.Gn9Z&  
5. 使用PutWorkspaceData发送照度数据到Matlab H\+-cvl  
6. 使用PutFullMatrix发送标量场数据到Matlab中 . r`[  
7. 用Matlab画出照度数据 =l,#iYJP8  
8. 在Matlab计算照度平均值 _}ele+  
9. 返回数据到FRED中 ,sI35I J
