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。 @c{Z?>dUc#  
#}B~V3UD  
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: N>gv!z[E  
enableservice('AutomationServer', true) }>p)|Y T"/  
enableservice('AutomationServer') TuX#;!p6  
F oEZ1O<  
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。 [F6=JZ  
jo"[$%0`  
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: v#nFPB=z  
1. 在FRED脚本编辑界面找到参考. no;Yu  
2. 找到Matlab Automation Server Type Library &[kwM3 95  
3. 将名字改为MLAPP ;vd%=vR  
T!/$ @]%\7  
.j;My%)?p  
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。 ); $~/H4

现在将脚本代码公布如下,此脚本执行如下几个步骤: Nzr zLK  
1. 创建Matlab服务器。 6?hv ,^  
2. 移动探测面对于前一聚焦面的位置。 8LkC/  
3. 在探测面追迹光线 ;GvyL>|-~  
4. 在探测面计算照度 hz )L+  
5. 使用PutWorkspaceData发送照度数据到Matlab 7dW9i7Aj  
6. 使用PutFullMatrix发送标量场数据到Matlab中 h~F uuL  
7. 用Matlab画出照度数据 N5~g:([k  
8. 在Matlab计算照度平均值 H:0-.a^ZS  
9. 返回数据到FRED中 <'s1+^LC
