FRED案例-FRED如何调用Matlab

B&_Z&H=  
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。 jGT|Xo>t  
Gpi_p  
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: w=3 j'y{f  
enableservice('AutomationServer', true) sPVE_n  
    enableservice('AutomationServer') |3 Iug  
=:!>0~  
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。 e=aU9v L  
wS+!>Q_]w  
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|T%L4)  
1. 在FRED脚本编辑界面找到参考. v??$z#1F3  
2. 找到Matlab Automation Server Type Library ' sNiJ>  
    3. 将名字改为MLAPP W;l0GxOxQ  
     .;qh>Gt  
     }"SqB{5e(  
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。 e]CoYuPr

现在将脚本代码公布如下,此脚本执行如下几个步骤: I>##iiKN  
1. 创建Matlab服务器。 C/H;|3.X  
2. 移动探测面对于前一聚焦面的位置。 z&Aya*0v`  
3. 在探测面追迹光线 y. 1F@w|  
4. 在探测面计算照度 m OE!`fd  
5. 使用PutWorkspaceData发送照度数据到Matlab CJ7S5   
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ly35n`  
7. 用Matlab画出照度数据 ]T)<@bmL  
8. 在Matlab计算照度平均值 k{=dV  
9. 返回数据到FRED中 t`{T:Tjc
