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。 v\"S Gc  
JS>Gd/Jd  
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: /q$,'^.A  
enableservice('AutomationServer', true) zf>5,k'x'A  
enableservice('AutomationServer') -TOIc%  
h"[+)q%L  
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。 hyT1xa  
i^!ez5z  
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: ? j 9|5*  
1. 在FRED脚本编辑界面找到参考. uH;-z_Wpn!  
2. 找到Matlab Automation Server Type Library rzI|?QaPi  
3. 将名字改为MLAPP T!}[yW  
#vqo -y7@  
I;?X f  
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。 H<G4O02i_

现在将脚本代码公布如下,此脚本执行如下几个步骤: on7I l  
1. 创建Matlab服务器。 35x 0T/8  
2. 移动探测面对于前一聚焦面的位置。 :ECi+DxBK  
3. 在探测面追迹光线 Zf>^4_x3P  
4. 在探测面计算照度 G^1b>K  
5. 使用PutWorkspaceData发送照度数据到Matlab s $*'^:   
6. 使用PutFullMatrix发送标量场数据到Matlab中  X}6#II  
7. 用Matlab画出照度数据 cubk]~VD  
8. 在Matlab计算照度平均值 Fv)7c4  
9. 返回数据到FRED中 ro[Y-o5Q0
