[推荐]FRED案例-FRED如何调用Matlab [复制链接]

{)+/w"^.  
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。 xnArYm  
l!1bmg#]$  
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： 7W*OyH^  
enableservice('AutomationServer', true) >v(Xc/oI
 
    enableservice('AutomationServer') uBM1;9h  
N4Ym[l  
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。 @[^H*^1|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： c;WS !.  
1. 在FRED脚本编辑界面找到参考. ]b[3 th*  
2. 找到Matlab Automation Server Type Library `hbM2cM  
    3. 将名字改为MLAPP U|>Js!$

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。 Xd4~N:

现在将脚本代码公布如下，此脚本执行如下几个步骤： Zy<0'k%U  
1. 创建Matlab服务器。 I;No++N0  
2. 移动探测面对于前一聚焦面的位置。 ;gF"o5/Q  
3. 在探测面追迹光线 aW"BN 5eM>  
4. 在探测面计算照度 qRr;&M &t_  
5. 使用PutWorkspaceData发送照度数据到Matlab yVW)DQ4?  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 \d6A<(!=v  
7. 用Matlab画出照度数据 6K,AQ.=V2  
8. 在Matlab计算照度平均值

9. 返回数据到FRED中 R_-.:n%.z
