FRED案例-FRED如何调用Matlab

{E; bT|3z  
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。 V408u y-M  
6hMKAk  
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: @ ]40xKF  
enableservice('AutomationServer', true) 4O{G^;  
    enableservice('AutomationServer') [~PR\qm  
U9ZuD40\  
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。 I8a3:)

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: WkiPrQ0]:  
1. 在FRED脚本编辑界面找到参考. c]h@<wnv  
2. 找到Matlab Automation Server Type Library ua"2nVxK_K  
    3. 将名字改为MLAPP uu9IUqEq2  
     O\CnKNk,  
     )s,LFIy<A  
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。 9: .m]QN

现在将脚本代码公布如下,此脚本执行如下几个步骤: iciKjXJ :  
1. 创建Matlab服务器。 w3ATsIw  
2. 移动探测面对于前一聚焦面的位置。 *|<T@BXn  
3. 在探测面追迹光线 C6EGM/m8  
4. 在探测面计算照度 J%-4ZB"  
5. 使用PutWorkspaceData发送照度数据到Matlab `m#-J;la  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _1Q6FI5iR  
7. 用Matlab画出照度数据 GGnlkp& E  
8. 在Matlab计算照度平均值 S)g:+P  
9. 返回数据到FRED中 41R6V>e@9J
