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。 7 [0L9\xm  
{z|;Xi::"  
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: >t7x>_~   
enableservice('AutomationServer', true) Y".RPiTL  
enableservice('AutomationServer') y|wc ,n%L>  
r7qh>JrO  
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。 =FD;~

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: }l=xiAF  
1. 在FRED脚本编辑界面找到参考. g:EVhuK  
2. 找到Matlab Automation Server Type Library <I;2{*QI2  
3. 将名字改为MLAPP G}p\8Q}'

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。 G z)NwD

现在将脚本代码公布如下,此脚本执行如下几个步骤: c/ uNM  
1. 创建Matlab服务器。 ,cq F3   
2. 移动探测面对于前一聚焦面的位置。 /7 Cn(s5o  
3. 在探测面追迹光线 !^ _ "~  
4. 在探测面计算照度 YID4w7|  
5. 使用PutWorkspaceData发送照度数据到Matlab ~zw]5|  
6. 使用PutFullMatrix发送标量场数据到Matlab中 M+x,opl  
7. 用Matlab画出照度数据 mml z&h  
8. 在Matlab计算照度平均值 b6*!ACY  
9. 返回数据到FRED中 * oybD=%4
