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。 {A0F/#M]  
UJ}}H}{  
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: m=6?%' H}  
enableservice('AutomationServer', true) oT{9P?K8  
enableservice('AutomationServer') SSF:PTeG>  
eV?%3h.   
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。 ExO#V9DaW  
|-=-/u1  
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: t`JT  
1. 在FRED脚本编辑界面找到参考. PL= v,NB  
2. 找到Matlab Automation Server Type Library aftt^h  
3. 将名字改为MLAPP ,5c7jZ5H

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。 */K[B(G

现在将脚本代码公布如下,此脚本执行如下几个步骤: Vl1.]'p_  
1. 创建Matlab服务器。 z#Jw?K_  
2. 移动探测面对于前一聚焦面的位置。 i`@cVYsL  
3. 在探测面追迹光线 P[ o"%NZ'  
4. 在探测面计算照度 C,W@C  
5. 使用PutWorkspaceData发送照度数据到Matlab e2=}qE7  
6. 使用PutFullMatrix发送标量场数据到Matlab中 PJB_"?NTTC  
7. 用Matlab画出照度数据 )2).kL>  
8. 在Matlab计算照度平均值 LkJq Bg  
9. 返回数据到FRED中 ZiR}S
