FRED案例-FRED如何调用Matlab

WF'Di4   
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。 WTlR>|Zdn  
Bu%TTbnz_G  
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: d9@Pze">e  
enableservice('AutomationServer', true) 8y9`xRy  
    enableservice('AutomationServer') .>/Tc  
5V"Fy&}:  
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。 zB/)_AW

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: 3U.?Jbm-8  
1. 在FRED脚本编辑界面找到参考. ~s$ jiA1  
2. 找到Matlab Automation Server Type Library }DCR(p rD  
    3. 将名字改为MLAPP '[T#d!T  
     )&jE<C0  
     {? a@UUvC  
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。 KNI* :

现在将脚本代码公布如下,此脚本执行如下几个步骤: 7 3 Oo;  
1. 创建Matlab服务器。 @i" ^b  
2. 移动探测面对于前一聚焦面的位置。 U]8 @  
3. 在探测面追迹光线 ~|FKl%  
4. 在探测面计算照度 bwr}Ge  
5. 使用PutWorkspaceData发送照度数据到Matlab r[u@ [  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JGLjx"Y  
7. 用Matlab画出照度数据 H#Aar  
8. 在Matlab计算照度平均值 bD: yu  
9. 返回数据到FRED中 u U|fCwQt
