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。 !#.\QU|  
?!H)zz6y  
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: :.DI_XN`  
enableservice('AutomationServer', true) @YCv  
enableservice('AutomationServer') g&bwtEZ  
e[}],W  
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。 B3Mx,uXT\

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^l*5F%DK  
1. 在FRED脚本编辑界面找到参考. _e_4Q)z-a  
2. 找到Matlab Automation Server Type Library dN<5JQql  
3. 将名字改为MLAPP Pw= 3PvkL  
lj*8mS/;h  
:Dayv6g  
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。 Ae6("Oid

现在将脚本代码公布如下,此脚本执行如下几个步骤: '6X%=f'^b  
1. 创建Matlab服务器。  |# V(p^  
2. 移动探测面对于前一聚焦面的位置。 -1CEr_(P^  
3. 在探测面追迹光线 *="m3:c'J  
4. 在探测面计算照度 @89I#t6A.  
5. 使用PutWorkspaceData发送照度数据到Matlab [^M|lf   
6. 使用PutFullMatrix发送标量场数据到Matlab中 izf~w^/  
7. 用Matlab画出照度数据 7 W{~f?Sh  
8. 在Matlab计算照度平均值 O~6Q;qP  
9. 返回数据到FRED中 xZyeX34{M;
