[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。 %gqu7}'  
PM:u~D$Jd  
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： 5}9rp
N{y  
enableservice('AutomationServer', true) C?g*c
  
enableservice('AutomationServer') L?(1 [jB4G  
}p9#Bzc  
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。 1TN+pmc}@

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： ZQ\O| n8  
1. 在FRED脚本编辑界面找到参考. ^D {v L  
2. 找到Matlab Automation Server Type Library 7W/55ZTmJ  
3. 将名字改为MLAPP i94)DWZ^

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。 R|O^7o

1. 创建Matlab服务器。 riglEA[^  
2. 移动探测面对于前一聚焦面的位置。 I'R|B\  
3. 在探测面追迹光线 srU*1jD)  
4. 在探测面计算照度 ~05(92bK  
5. 使用PutWorkspaceData发送照度数据到Matlab ~X) 1!Sr  
6. 使用PutFullMatrix发送标量场数据到Matlab中 fdKTj =4  
7. 用Matlab画出照度数据 f5CnJhE|)  
8. 在Matlab计算照度平均值 p!LaR.8]  
9. 返回数据到FRED中 VpM(}QHd
