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。 :vr,@1c  
G'epsD,.bX  
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: (r|T&'yK  
enableservice('AutomationServer', true) [X I5Bu ~  
enableservice('AutomationServer') m<yA] ';s  
c`>\R<Z ]  
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。 :X!(^ a;]  
=UV?Pi*M>  
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: zZxP= c  
1. 在FRED脚本编辑界面找到参考. Za} |Ee  
2. 找到Matlab Automation Server Type Library -Z Z$ 1E  
3. 将名字改为MLAPP NqWHR~&  
5A)w.i&V  
Z 0:2x(x9  
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。 lfA  BF

现在将脚本代码公布如下,此脚本执行如下几个步骤: 7m jj%  
1. 创建Matlab服务器。 d#*5U9\z  
2. 移动探测面对于前一聚焦面的位置。 8N`$7^^  
3. 在探测面追迹光线 e!8_3BE  
4. 在探测面计算照度 d5%*^nMpY  
5. 使用PutWorkspaceData发送照度数据到Matlab /;0>*ft4  
6. 使用PutFullMatrix发送标量场数据到Matlab中 gv,T<A?Z2  
7. 用Matlab画出照度数据 =6dKC_Q  
8. 在Matlab计算照度平均值 C0W~Tk\C2  
9. 返回数据到FRED中 SQ!lgm1bA
