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。 fh)eL<I  
n[!QrEeR},  
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: iP9]b&  
enableservice('AutomationServer', true) :^`j:B  
enableservice('AutomationServer') &D[M<7T  
y>t:flD*  
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。 \i,H1a  
FEu}zt@  
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: /y{fDCC  
1. 在FRED脚本编辑界面找到参考. -6-rX D  
2. 找到Matlab Automation Server Type Library tgCp2 `n  
3. 将名字改为MLAPP nHbi{,3  
wxK71OH  
%Bm{ctf#)  
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。 "zNS6I?rzE

现在将脚本代码公布如下,此脚本执行如下几个步骤: k0I$x:c  
1. 创建Matlab服务器。 t*Ro2QZ  
2. 移动探测面对于前一聚焦面的位置。 .4E24FB[f?  
3. 在探测面追迹光线 f eB ?  
4. 在探测面计算照度 mIG>`7`7N  
5. 使用PutWorkspaceData发送照度数据到Matlab ul N1z  
6. 使用PutFullMatrix发送标量场数据到Matlab中 1yF9zKs&_  
7. 用Matlab画出照度数据 H74'I}  
8. 在Matlab计算照度平均值 0&NM=~  
9. 返回数据到FRED中 q7aqbkwz}
