[推荐]FRED案例-FRED如何调用Matlab [复制链接]

N-;e" g  
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。 4K
:p  
6EJ,czt(  
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： iYBs )  
enableservice('AutomationServer', true) 8L.Y0_x  
    enableservice('AutomationServer') |UE&M3S  
2{g~6U.  
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。 "w=.2A:q

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： H7*/  
1. 在FRED脚本编辑界面找到参考. &R>x;&Gj  
2. 找到Matlab Automation Server Type Library +ImPNwrY  
    3. 将名字改为MLAPP |5`z;u7V

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。 {dhGSM7

1. 创建Matlab服务器。 (Z;-u+ }.  
2. 移动探测面对于前一聚焦面的位置。 5q}680s9+  
3. 在探测面追迹光线 PO]z'LD  
4. 在探测面计算照度 6O!&!  
5. 使用PutWorkspaceData发送照度数据到Matlab u-yQP@^H  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #:e52

7. 用Matlab画出照度数据 +.NopI3:  
8. 在Matlab计算照度平均值 n;y<!L7  
9. 返回数据到FRED中 O\=3{
