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。 >o #^r;  
jG=*\lK6  
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: V&4)B &W  
enableservice('AutomationServer', true) r2?-QvQ  
enableservice('AutomationServer') QW :-q(s  
3f9J! B`n  
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。 xzF@v>2S+  
b%>vhj&F  
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: iyNyj44 H  
1. 在FRED脚本编辑界面找到参考. JzH\_,,  
2. 找到Matlab Automation Server Type Library ?CGbnXZ4Ug  
3. 将名字改为MLAPP lV!ecJw$

xXQ#?::m  
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。 'T@K$xL8

现在将脚本代码公布如下,此脚本执行如下几个步骤: 1c);![O  
1. 创建Matlab服务器。 `-!t8BH  
2. 移动探测面对于前一聚焦面的位置。 3DRbCKNL  
3. 在探测面追迹光线 T'.U?G  
4. 在探测面计算照度 J<dr x_gc  
5. 使用PutWorkspaceData发送照度数据到Matlab a>A29*q  
6. 使用PutFullMatrix发送标量场数据到Matlab中 + 5E6|  
7. 用Matlab画出照度数据 !J ")TP=  
8. 在Matlab计算照度平均值 \YO1;\W  
9. 返回数据到FRED中 ]5IG00`
