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。 USrg,A  
qp@:Zqz8  
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: QX$i ]y%S  
enableservice('AutomationServer', true) s]p3dB#  
enableservice('AutomationServer') L>qLl_.  
;v?!Pml2k  
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。 6 NJ5v +  
7k>sE  
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: a ykNH>#Po  
1. 在FRED脚本编辑界面找到参考. fGD#|a;,  
2. 找到Matlab Automation Server Type Library '[h|f  
3. 将名字改为MLAPP 8yDu(.Q  
C$1}c[  
%kg%ttu7  
在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 5$|wW}SA

现在将脚本代码公布如下,此脚本执行如下几个步骤: K 8gd?88  
1. 创建Matlab服务器。 u K`T1*_  
2. 移动探测面对于前一聚焦面的位置。 K] ^kUN_  
3. 在探测面追迹光线 'RlPj 0Cg  
4. 在探测面计算照度 ;J[1S  
5. 使用PutWorkspaceData发送照度数据到Matlab v_gQCS  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ]B<Hrnn  
7. 用Matlab画出照度数据 U[a;e OLx  
8. 在Matlab计算照度平均值 tCk;tu!d  
9. 返回数据到FRED中 T{iv4`'
