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。 [=*E+Oc  
G)>W'yxQ  
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: 6`\]derSon  
enableservice('AutomationServer', true) ngulcv  
enableservice('AutomationServer') ,(G%e  
_ nT{g  
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。 V@=V5bZLs  
vAP{;Q0 i  
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: 7=4A;Ybq  
1. 在FRED脚本编辑界面找到参考. O\;=V`z-  
2. 找到Matlab Automation Server Type Library ~#:e*:ro  
3. 将名字改为MLAPP k6IG+:s  
dEM ?~?  
'UM!*fk7C  
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。 ghk5rl$

现在将脚本代码公布如下,此脚本执行如下几个步骤: \o3"~\|6C  
1. 创建Matlab服务器。 $mco0 %$  
2. 移动探测面对于前一聚焦面的位置。 iZ[tHw||  
3. 在探测面追迹光线 BH0!6Oq  
4. 在探测面计算照度 dw@E)  
5. 使用PutWorkspaceData发送照度数据到Matlab -7'#2P<)  
6. 使用PutFullMatrix发送标量场数据到Matlab中 aI#4H+/  
7. 用Matlab画出照度数据 ^c9ThV.v  
8. 在Matlab计算照度平均值 Mj0Cat=  
9. 返回数据到FRED中 ?SY<~i<K-
