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。 h}U\2$5  
?=uw0~O[  
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: z<F.0~)jb  
enableservice('AutomationServer', true) R]Q4+  
enableservice('AutomationServer') P2Ja*!K]  
QAy9RQ0  
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。 X;ZR"YgT

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: ?DC3BA\)  
1. 在FRED脚本编辑界面找到参考. F W# S.<  
2. 找到Matlab Automation Server Type Library X=p~`Ar M{  
3. 将名字改为MLAPP q_N8JQg  
?_F,HhQ  
TvWhy`RQ  
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。 EO;f`s)t

现在将脚本代码公布如下,此脚本执行如下几个步骤: P~0d'Oi  
1. 创建Matlab服务器。 khb Gyg%  
2. 移动探测面对于前一聚焦面的位置。 X~Li`  
3. 在探测面追迹光线 %XqLyeOS  
4. 在探测面计算照度 -< 7KW0CA  
5. 使用PutWorkspaceData发送照度数据到Matlab t p.qh]2c  
6. 使用PutFullMatrix发送标量场数据到Matlab中 S`"M;%T  
7. 用Matlab画出照度数据 ud`.}H~aB  
8. 在Matlab计算照度平均值 q*ZjOqj  
9. 返回数据到FRED中 1px:(8]{
