[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。 3

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： \k]x;S<a  
enableservice('AutomationServer', true) N0K){  
enableservice('AutomationServer') v~T7`   
`%E8-]{uS  
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。 cooUE<a

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： |\dZ'   
1. 在FRED脚本编辑界面找到参考. ZxG}ViS4I  
2. 找到Matlab Automation Server Type Library 'Q =7/dY3I  
3. 将名字改为MLAPP }<>~sy

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。 R64!>o"nED

现在将脚本代码公布如下，此脚本执行如下几个步骤： R g?1-|Tj  
1. 创建Matlab服务器。 YXU|h  
2. 移动探测面对于前一聚焦面的位置。 KJ?y@Q  
3. 在探测面追迹光线 ;Og&FFs'  
4. 在探测面计算照度 '=E3[0W  
5. 使用PutWorkspaceData发送照度数据到Matlab +&X%<
S W  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ]Ni;w]KE  
7. 用Matlab画出照度数据 Nrah;i+H\o  
8. 在Matlab计算照度平均值 !Oj)B1gc6&  
9. 返回数据到FRED中 Z2Zq'3*
