[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。 "(W;rl  
,<K+.7,)E  
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： cy(w*5Upu  
enableservice('AutomationServer', true) &qPezyt  
enableservice('AutomationServer') FXY>o>K%h  
gi/k#3_m  
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。 iex%$> "  
t\QLj&h}E  
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： @8`I!fZ  
1. 在FRED脚本编辑界面找到参考. MC,Qv9m  
2. 找到Matlab Automation Server Type Library ?5ZvvAi  
3. 将名字改为MLAPP Opf)TAl{

>Q(\vl@N=  
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。 Bca$%3

现在将脚本代码公布如下，此脚本执行如下几个步骤： \$4z@`nY  
1. 创建Matlab服务器。 iNl<<0a  
2. 移动探测面对于前一聚焦面的位置。 F[O147&C  
3. 在探测面追迹光线 IFr"IOr'l  
4. 在探测面计算照度 !D{z. KO  
5. 使用PutWorkspaceData发送照度数据到Matlab d)biMI}<5  
6. 使用PutFullMatrix发送标量场数据到Matlab中 OSUiS`k  
7. 用Matlab画出照度数据 p`7d9MV^  
8. 在Matlab计算照度平均值 mYJ8O$  
9. 返回数据到FRED中 I*o6Bn |D
