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。 wtgO;w  
U:5*i  
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: ht[TMdV  
enableservice('AutomationServer', true) ud~VQXZo  
enableservice('AutomationServer') ]cO$E=W  
JY,l#?lM{  
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。 brhJ&|QDE  
sO f)/19  
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: d T0 z^SG  
1. 在FRED脚本编辑界面找到参考. eJwii  
2. 找到Matlab Automation Server Type Library 0ju wDd  
3. 将名字改为MLAPP <?`e9o  
kY |=a  
{t IoC;Y  
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。 #@OKp,LJ

现在将脚本代码公布如下,此脚本执行如下几个步骤: ^ 8Nr %NJ  
1. 创建Matlab服务器。 A<G ;  
2. 移动探测面对于前一聚焦面的位置。 66y,{t  
3. 在探测面追迹光线 _ER cmP  
4. 在探测面计算照度 ]a@v)aa-  
5. 使用PutWorkspaceData发送照度数据到Matlab $@ #G+QQ_  
6. 使用PutFullMatrix发送标量场数据到Matlab中 #$ raUNr  
7. 用Matlab画出照度数据 @5nkI$>3z  
8. 在Matlab计算照度平均值 P)o[p(  
9. 返回数据到FRED中 u+i/CE#w
