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。 sD{Wc%5  
2@ZRz%(Oa&  
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: 7ju38@+  
enableservice('AutomationServer', true) ?(Plb&kR  
enableservice('AutomationServer') zA3r&stN+  
yxf #@Je"  
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。 $T7 qd  
M:&%c3  
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: b9-3  
1. 在FRED脚本编辑界面找到参考. R1%J6wZq  
2. 找到Matlab Automation Server Type Library 7(^F@,,@  
3. 将名字改为MLAPP V3a6QcG  
n^5Q f\o  
Gui[/iY,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。 G^dzE/ :

现在将脚本代码公布如下,此脚本执行如下几个步骤: Rxlv:  
1. 创建Matlab服务器。 a{rUk%x  
2. 移动探测面对于前一聚焦面的位置。 !u  .n  
3. 在探测面追迹光线 kDM?`(r  
4. 在探测面计算照度 l]&x~K}  
5. 使用PutWorkspaceData发送照度数据到Matlab ]gaeN2  
6. 使用PutFullMatrix发送标量场数据到Matlab中 QF*cdc<  
7. 用Matlab画出照度数据 )"6"g9A  
8. 在Matlab计算照度平均值 Wyeb1  
9. 返回数据到FRED中 hJir_=
