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。 cL-[ZvyVX  
+M./@U*g  
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: spGb!Y`mR  
enableservice('AutomationServer', true) 9`T)@Uj2n  
enableservice('AutomationServer') ~xbe~$$Q@  
Gk. ruQW"  
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。 &Q%zl9g(g

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: ")_|69 VX  
1. 在FRED脚本编辑界面找到参考. &D >G8  
2. 找到Matlab Automation Server Type Library h2)yq:87  
3. 将名字改为MLAPP 0QB iC]9

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。 _- [''(E

现在将脚本代码公布如下,此脚本执行如下几个步骤: <>n0arAn  
1. 创建Matlab服务器。 9 3U_tQ&1?  
2. 移动探测面对于前一聚焦面的位置。 <vnHz?71c  
3. 在探测面追迹光线 GSY(  
4. 在探测面计算照度 Kh"?%ZIa  
5. 使用PutWorkspaceData发送照度数据到Matlab jG6]A"pr  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Z_PNI#h*  
7. 用Matlab画出照度数据 :lX!\(E2  
8. 在Matlab计算照度平均值 ~9?cn  
9. 返回数据到FRED中 [=x[ w70
