FRED如何调用Matlab

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。 $rmxwxz&W:  
Zk((VZ(y  
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: sTl^j gV7j  
enableservice('AutomationServer', true) [,,@>nyD  
enableservice('AutomationServer') L"vrX  
6qFzo1LO  
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。 \}v@!PQl

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: eyJWFJh  
1. 在FRED脚本编辑界面找到参考. oI/_WY[t  
2. 找到Matlab Automation Server Type Library 7PMz6  
3. 将名字改为MLAPP Rw{' O]Q*  
j \jMN*dmV  
[*p;+&+/ZM  
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。 hmo4H3g!N

现在将脚本代码公布如下,此脚本执行如下几个步骤: RU7+$Z0K  
1. 创建Matlab服务器。 ?.Vuet  
2. 移动探测面对于前一聚焦面的位置。 (WC =om  
3. 在探测面追迹光线 JX&]>#6|E  
4. 在探测面计算照度 v#&;z_I+  
5. 使用PutWorkspaceData发送照度数据到Matlab Gg9s.]W  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~*/ >8R(Y  
7. 用Matlab画出照度数据 mMwV5\(  
8. 在Matlab计算照度平均值 XXum2eA  
9. 返回数据到FRED中 +bLP+]7oZ
