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。 j<^!"_G]*?  
{hS!IOM  
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: 2C S9v  
enableservice('AutomationServer', true) ASXGM0t  
enableservice('AutomationServer') \+o\wTW  
Myc-lCE  
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#0n2o#

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: %1#\LRA(  
1. 在FRED脚本编辑界面找到参考. E1QJ^]MG.  
2. 找到Matlab Automation Server Type Library +5y^c |L0  
3. 将名字改为MLAPP B!'K20"gF  
//8W">u  
T}Tv}~!f  
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。 u&~Xgq5[

现在将脚本代码公布如下,此脚本执行如下几个步骤: kK5&?)3Y:  
1. 创建Matlab服务器。 C%4ed#  
2. 移动探测面对于前一聚焦面的位置。 HI5NWdfRl  
3. 在探测面追迹光线 24wDnDyh  
4. 在探测面计算照度 D,IT>^[^7  
5. 使用PutWorkspaceData发送照度数据到Matlab kff N0(MR  
6. 使用PutFullMatrix发送标量场数据到Matlab中 -ssb|r  
7. 用Matlab画出照度数据 P& 1$SWNyW  
8. 在Matlab计算照度平均值 hb3n- rO  
9. 返回数据到FRED中 YnpN -Y%g
