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。 d~s-;T  
\nt'I;f  
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: {.'g!{SHp  
enableservice('AutomationServer', true) 8y )i,"  
enableservice('AutomationServer') xo3)ds X  
 ]@ 0V  
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。 ~$9"|

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: ^HKaNk<  
1. 在FRED脚本编辑界面找到参考. JugQ +0  
2. 找到Matlab Automation Server Type Library a'.=.eDQ  
3. 将名字改为MLAPP 3Jit2W4  
SQCuY<mD  
D#(Pg  
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。 ,$*klod

现在将脚本代码公布如下,此脚本执行如下几个步骤: J8[Xl.  
1. 创建Matlab服务器。 e q.aN3KB"  
2. 移动探测面对于前一聚焦面的位置。 sMo%Ayes  
3. 在探测面追迹光线 RLr-xg$K-t  
4. 在探测面计算照度 .j,&/y&  
5. 使用PutWorkspaceData发送照度数据到Matlab unB "dE  
6. 使用PutFullMatrix发送标量场数据到Matlab中 -Euy5Y  
7. 用Matlab画出照度数据 s7gf7 E#Y  
8. 在Matlab计算照度平均值 +1A<kJ  
9. 返回数据到FRED中 U4/$4.'NQ
