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。 \gZjq]3  
[nsTO5G$u  
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: QmPHf*w[  
enableservice('AutomationServer', true) *i7-_pT  
enableservice('AutomationServer') .W-=VzWX  
=PBJ+"DQs  
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。 +w3k_^X9c

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: U@:iN..  
1. 在FRED脚本编辑界面找到参考. !.{{QwZ  
2. 找到Matlab Automation Server Type Library C%Op[H3  
3. 将名字改为MLAPP uUpOa+t  
H&ZsMML/%  
}W]k1Bsx  
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。 ==7=1QfP

现在将脚本代码公布如下,此脚本执行如下几个步骤: Y2p~chx9  
1. 创建Matlab服务器。 "l09Ae'V  
2. 移动探测面对于前一聚焦面的位置。 J&b&*3   
3. 在探测面追迹光线 ZZ;V5o6E  
4. 在探测面计算照度 oakm{I|k}  
5. 使用PutWorkspaceData发送照度数据到Matlab 1Yv#4t  
6. 使用PutFullMatrix发送标量场数据到Matlab中 b{JxTT}03  
7. 用Matlab画出照度数据 ?K?v64[  
8. 在Matlab计算照度平均值 3D7phq>.q  
9. 返回数据到FRED中 J 9k~cz
